Python - Variables (Day 1)

This is a 100 Days challenge to learn a new language (Python). 100 Days of Code - The Complete Python Pro Bootcamp 

I will post some notes to motivate myself to finish this challenge.

Printing Function

Ex:

# Below are all valid

print("Hello World!")

print('Hello World!')

print("Hello 'World'!")

print('Hello "World"!')

Result:

Hello World! Hello World! Hello 'World'! Hello "World"!

Input Function

Ex:

# Get user input

name = input("What's your name?")

print("Hello " + name + "!")

Result:

What's your name?Frank Hello Frank!

Ex:

my_name = 'Frank'

name = '1'

Name = '1'

_name = '1'

Python Comment

Using '#' instead of '/' or

Ex:

# This is a comment

Note

Unlike other language, python should not contain unexpected indent.
