Strings in python tutorial for beginners 2022

Alright in this guide we are going to explore Python strings. how strings work, what functions we have, most used functions and so on

String in Python

So here is a example for string

// Simple string

"any text goes here" or "single word"

To print the value we use

// Print values

// print variable value

print(variable_name)

// Print variable type

print(type(variable_name))

Define a string and assign it to variable in Python

// Defining a first_name string and assigning to variable

first_name = 'Roger'

Concatenating Two strings

first_name = 'Roger'
last_name = ' smith'

output = first_name + last_name

output -> Roger smith

Get user input as string in Python

Here we get user input and assign it to variable "first_name".

first_name = input("Please enter your name")
print_r(first_name)

isdigit()      // checks is string is numbers only returns true or false
isalnum()      // checks is string is has alpha or number returns true if either type is present

find()        // finds substring in string returns index or -1
index()        // finds substring in string returns index or error

len()         // returns length of string
strip()         // removes specific values from string.
