Why String Manipulation
All programming languages allow you to manipulate strings, it is an essential skill and function. You could use it to find a value within a string, use it to select only a part of the string and so on.
String Manipulation in Python
Print a String
str = 'Hello World!'
print (str) # Prints complete string
Get a Character from a String
str = 'Hello World!'
print (str[0]) # Prints first character of the string, or any character at the element provided so str[3] will get the 4th character
Get a Selection of the String from the Middle
str = 'Hello World!'
print (str[2:5]) # Prints characters starting from 3rd to 5th, this allows you to select a part of a string
Get a Selection of the String from the Start or End
str = 'Hello World!'
print (str[2:]) # Prints string starting from 3rd character until the end
print (str[:2]) # Prints string starting from the start and upto the 3rd character
Repeating String
str = 'Hello World!'
print (str * 2) # Prints string two times
String Concatenation
str = 'Hello World!'
print (str + "TEST“) # Prints concatenated string
