To see what you are doing, you can tell python to output something.
In python, that is done with the
print function.
print(what eva you want)
If you ran the code:
print('Hello World')
print(5.0)
Python would output:
Hello World
5.0
To associate values with a name you create, you can use
=.
Name of your variable = Value of the variable.
If you ran the code:
x = 5
print(x+5)
print(x-3)
print(x)
Python would output:
10
2
5
To run code in strings, you can use type f in front of your string.
f"Wow you can run {code} in strings!"
Note: Refrain from placing strings in
{code}. It returns hard to debug errors.
If you ran the code:
x = 5.5
print(f"{x} + 5.75 = {x+5.75}")
print(f'{x} - 3 = {x-3}')
print(f"x is {x}")
Python would output:
5.5 + 5.75 = 11.25
5.5 - 3 = 2.5
x is 5.5
If you want to let the user to input information.
You can use the
input function.
input('What is the question? ')
If you ran the code:
name = input('What is your name? ')
print(f'Hello {name}!')
Python would output:
What is your name? John
Hello John!
