How to reverse a string in python
1 min readMay 22, 2021
A Brief About Strings-
- The String is a data type in Python that has a sequence of characters. This series of characters are represented in single, double or triple quotes. Python has a built-in string class called ‘str’.
For example-
Name=’Darcy’
Nationality=” British”
Message= “Hello World”
- The characters of strings can be accessed using the indexes. The expression [ ] in brackets is called an index.
For example-
message = “TENET”
The characters of this string can be accessed as-
message [0] = T
message [1] = E
message [2] = N
message [3] = E
message [4] = T
- They are immutable which means they cannot be changed. A new string is created when we try to change or modify the existing string variable. Using id(), we can get the memory addresses of objects.
- The feature of slicing present in strings can help us to fetch the characters of our choice. The syntax of slice operation is s[start:end].
Start specifies the beginning index of the substring.
End specifies the last character index of the substring.
a=’CORSICA’ OUTPUT
print(a[1:5]) ORSI
print(a[1:]) ORSICA
print(a[:6]) CORSIC
- Regular Expressions are an influential tool for different kinds of manipulation of our strings. They can be accessed using the re module.
