You have your else statement indented but it should be lined up with the corresponding if statement. Your else statement and the subsequent print should be un-indented 1 level. Yes, in python indentation is very important because that's what decides which lines of code belong to which blocks. Can you 360 mopar engine the error you're getting as well as the current code you're trying?

I had no idea that indentation can interfere with running a function. With that being said, it still gives me the same error! Your print statement that's part of the else should be indented one level.
It looks like you're trying to run your python command from within the python environment. That makes so much sense now that you said it! Glad you got it working!Before we get started, you should have a basic understanding of what Python is and some basic knowledge about its use. For more information on that and how you enable it on Windows 10, go here. The way Python executes a code block makes it execute each line in order, checking dependencies to import, reading definitions and classes to store in memory, and executing pieces of code in order allowing for loops and calls back to the defined definitions and classes.
If we want to tell when a Python program exits without throwing an exception, we can use the built-in Python atexit module. The atexit handles anything we want the program to do when it exits and is typically used to do program clean up before the program process terminates. Open the input. What if we get bad input from a user?
Notice how the process failed to complete when the function was told to wait for 7 seconds but completed and printed what it was supposed to when it was told to wait 0 seconds! If we have a loop in our Python code and we want to make sure the code can exit if it encounters a problem, we can use a flag that it can check to terminate the program.
In a previous tutorial, we talked about NumPy arrays, and we saw how it makes the process of reading, parsing, and performing operations on numeric data a cakewalk. In this tutorial, we will discuss the NumPy loadtxt method that is used to parse data from text files and store them in an n-dimensional NumPy array. Pandas is an open-source Python library that provides data analysis and manipulation in Python programming. The most important piece in pandas is the DataFrame, where you store and play with the data.
In this tutorial, you will learn what the DataFrame is, how […]. The zip function in Python programming is a built-in standard function that takes multiple iterables or containers as parameters. An iterable in Python is an object that you can iterate over or step through like a collection. You can use the zip function to map the same indexes of more than one iterable. Mapping these […].

In this post, we will learn how to print in Python, and how to do a couple of slightly more advanced things, such as showing strings and other variables. However, this is very slightly complicated by the fact that there are two popular versions of Python.
Strings can also be stored as variables. This means you will use a word in order to represent the string, and then refer to it later on in your code.
We can then later print that text. To print a variable such as a string, we simply place it inside the brackets without the quotation marks. Why might you want to print a variable like this? Well, this becomes useful any time you think you might want the content you show to change during the course of your program.
And this also shows you how to print in Python when combining a variable with some text. Simply close the quotation marks and then use the plus symbol. Notice that I inserted the space? Another way you can do this is to separate the elements you want to print using a comma. For example:. Another option is to follow your print statement with another blank print statement:. Finally, note that you can use either double or single quotes. This will then allow you to include those characters within your string:.

Let's begin This is using a named argument name and assigning your variable to it. Let's begin This is using just a positional argument.Every program is eventually a data processor, so we should know how to input and output data within it.
There exists a function, printto output data from any Python program. To use it, pass a comma separated list of arguments that you want to print to the print function. Let's see an example. To input data into a program, we use input.
This function reads a single line of text, as a String. Here's a program that reads the user's name and greets them: John print 'What is your name? Let's try to write a program that inputs two numbers and prints their sum.
On the left side of an assignment operator we put the name of the variable. On the right side of an assignment operator we put any expression that Python can evaluate.
The name starts pointing to the result of the evaluation.
name = input ("whats your name? ")
After running the example we can see that it prints So, the program is wrong, and it's important to understand why. The sum of two strings in Python works as follows: they are just glued one after another. It's also sometimes called "string concatenation". That means that the values there are string, not numbers. Strings and numbers are represented in Python differently. All the values in Python are called "objects".
Every object has a certain type. The number 2 corresponds to an object "number 2" of type "int" i. The string 'hello' corresponds to an object "string 'hello'" of type "str".
Every floating-point number is represented as an object of type "float". The type of an object specifies what kind of operations may be applied to it. For instance, if the two variables "first" and "second" are pointing to the objects of type intPython can multiply them. Apple sharing Previous and next Two timestamps School desks 2.

Functions and recursion 9. Two-dimensional lists arrays In any programming language, including Python, output is always simpler than input. So, we will start off looking at simple output. Simple output is one of the first things that you would learn when learning a new programming language.
This is because output is one of the basic programming constructs and simple output is the easiest kind of output to use. Simple output is just the printing of text to the console. In Python, the function used to perform simple output is the print function.
Here is a one line Python program that illustrates how the print function can be used:. The actual prompt you see in the console will usually consist of something like this:. Each time the print function is called, the next call of the print function will be printed to the next line. Here is a simple program with several print statements:. Sometimes we want to print multiple values on the same line.
The easiest way to do this is to follow print with those values separated by commas. This is shown in the next example:. Notice how the print function prints a literal string "x is" followed by the value of x all on the same line. When you separate the values by commas, the print function automatically inserts a space between the values.
A literal string is a group of characters that is enclosed in quotes. When you print out a literal string, the output is literally everything that is in between the quotes. Placing a comma at the end of a print statement will cause the next output from a print statement to be on the same line providing there is space.
Python | Output using print() function
Look at the next program to see an example of this:. The print statements on lines 1, 2 and 3 all set the end character to a space. Therefore, the output from all of the print statements will be on the same line separated with a space. Here is a sample run of the program:. In Python2 this could have been done using commas at the end of each print statement. This would have automatically added a space between each output.
Suppose you want to output more than one value, but you don't want a space to be inserted between the values. In Python2, the way to avoid the spaces is to concatenate the values together. Concatenation is the combining of two strings. Here is a simple program showing the difference between concatenation and separating values using a comma:. The first line of output shows "hot" and "dog" separated by a space.
This is because those values were separated by a comma when printed. The second line of output shows "hotdog" without any spaces, because the two strings were concatenated before printing. Concatenation is something that can be used to combine two strings. However, you cannot use concatenation to combine a string and a number. Here is a program that results in an error when run because the programmer attempted to concatenate a string and a number:.
This can easily be fixed by converting the number into its string representation using the str function.What are Exponents? - Don't Memorise
This is shown in the corrected version of the program. The str function does not exactly convert a number into a string. The str function returns the string representation of any Python object, whether it is a number, a string, or some other object like a Python list.
