String in Python

Python strings are referred to as a sequence of characters/letters that are either literal constants or some kind of variable surrounded by either single quotation marks, or double quotation marks.

The program code below demonstrates the printing of string.

# 'my_string' is a string
my_string = "Network Automation is a fun"
print(my_string)

Network Automation is a fun

In Python, single-quoted strings and double-quoted strings are the same. This PEP does not make a recommendation for this. Pick a rule and stick to it. When a string contains single or double quote characters, however, use the other one to avoid backslashes in the string. It improves readability.

—PEP 8, String Quotes

The Python program code below demonstrates a Python function to print the length of the character.

banner = "Welcome to Network Automation"
print(len(banner))  # len() returns the length

29

Warning

Don’t use the word ‘welcome’ in any type of banner on a network device.
