How do you put a quote mark inside a string that is wrapped in quote marks? Or a new line, or a tab? With a backslash \, which tells Python the next character means something special. The pair is called an escape sequence:

Write	Means
`\n`	new line
`\t`	tab
`\"`	a double quote
`\'`	a single quote
`\\`	one backslash

print("Line one\nLine two")
print("Name:\tAda")
print("She said \"hello\"")
print("C:\\Users\\Ada")

Often there is an easier route for quotes: wrap the string in the other kind. 'She said "hello"' needs no backslashes at all.
