How to capitalize first character of string in Python

Last Updated : 31 Dec, 2019

The problem of case changes a string is quite common and has been discussed many times. Sometimes, we might have a problem like this in which we need to convert the initial character of string to upper case. Let’s discuss certain ways in which this can be performed.

Method #1 : Using string slicing + upper()
This task can easily be performed using the upper method which uppercases the characters provided to it and slicing can be used to add the remaining string after the lowercase first character.

# Python3 code to demonstrate working of
# Initial character upper case
# Using upper() + string slicing
  
# initializing string 
test_str = "geeksforgeeks"
  
# printing original string 
print("The original string is : " + str(test_str))
  
# Using upper() + string slicing
# Initial character upper case
res = test_str[0].upper() + test_str[1:]
  
# printing result 
print("The string after uppercasing initial character : " + str(res))

Output :

The original string is : geeksforgeeks
The string after uppercasing initial character : Geeksforgeeks

Method #2 : Using capitalize()
We can use inbuilt method to perform this task. This method is recommended to solve this problem and performs the task of converting to upper case internally.

# Python3 code to demonstrate working of
# Initial character upper case
# Using capitalize() + string slicing
  
# initializing string 
test_str = "geeksforgeeks"
  
# printing original string 
print("The original string is : " + str(test_str))
  
# Using capitalize() + string slicing
# Initial character upper case
res = test_str.capitalize()
  
# printing result 
print("The string after uppercasing initial character : " + str(res))

Output :

The original string is : geeksforgeeks
The string after uppercasing initial character : Geeksforgeeks
