# Strings reference guide / tutorial for Python

# Print welcome message

print("Hello World")

# Strings can either be surrounded in " or '

print('Hello World')

# You can use variables to store strings, then print them out

message = "Hello World"

print(message)

# If you want to put single quotes in a single quote string or double quotes in a double quote string, you need to change the string's quote type

# Invalid: 'hello's world'

message = "hello's world" # Correct

# Invalid: "he said "welcome!""

message = 'he said "welcome!"' # Correct

# You can also use the backslash character to ignore quotes

message = 'mary\'s ice cream'

message = "she exclaimed \"good\" morning"

# Use three double quotes for a multiline string

message = """ hello

line1

line2

line3

...

"""
