Python - Check whether a string starts and ends with the same character or not
When it is required to check if a string begins and ends with the same character or not, regular expression can be used. A method can be defined that uses the ‘search’ function to see if a string begins and ends with a specific character.
Example
Below is a demonstration of the same
import re
regex_expression = r'^[a-z]$|^([a-z]).*\1$'
def check_string(my_string):
if(re.search(regex_expression, my_string)):
print("The given string starts and ends with the same character")
else:
print("The given string doesnot start and end with the same character")
my_string = "abcbabda"
print("The string is:")
print(my_string)
check_string(my_string)Output
The string is: abcbabda The given string starts and ends with the same character
Explanation
The required packages are imported.
A method named ‘check_string’ is defined that takes the string as a parameter.
The ‘search’ function is called by passing the string and the regular expression as parameters.

A substring is defined and is displayed on the console.
The method is called by passing the string and the substring.
