Strings & Things
Strings are any characters inside quotes.
print("This is a string with double quotes")
print('This is a string with single quotes')
# doesn't matter which quotes you use as long as you are consistent.
Python can’t evaluate anything inside of a string, so print('1+2') becomes: '1+2'.
What is the proper way to print the statement below:
It’s a Wonderful Life!
print( “It’s a Wonderful Life!’ )
print ( ‘It’s a Wonderful Life!’ )
print ( It’s a Wonderful Life! )
print ( “It’s a Wonderful Life!” )
String Methods
Built-in actions you can use on string data.
For example:
name = "sk"
print(name.upper())
message = "WHY ARE YOU YELLING!"
print(message.lower())
book = "to kill a mockingbird"
print(book.title())
.upper()
.title()
.lower()
We can also add strings together. In Python, this is called concatenation:
first_name = 'grace'
last_name = 'hopper'
name = first_name.title() + last_name.title()
print(name)
# What's the mistake?

Steve Jobs: "_____________quote_here_____________".
Option 2: In order to use a tab in your display you need to add \t in front of what you want printed.
For example: This code –>
print("\tThis creates a tab.")
will end up looking like –>
This creates a tab.
Find another quote and print the quote and the author but tab the author’s name on a new line after the quote.
