In a string you can include special characters(\t, \n, etc.)

Print: function to display data in the terminal.

print('Hello\nworld')

world

it can also define a string in multiple lines and include special characters with: """

"""
universe
	Earth
		plants	animals
"""

This is stored as:

'\nuniverse\n\tearth\n\t\tplants\tanimals'

The result on the screen with print is:

universe
	Earth
		plants	animals

Can addition and multiply strings using symbols: + and *.

# Addition
'Pacific' + 'ocean'

'Hi!'*3

'Hi!Hi!Hi!'

Escape the special characters use: \.

print('Hello\\nworld')
# output
'Hello\nworld'

Store the raw string it can use: r.

print(r'\route\tasks\new')
# output
'\route\tasks\new'
