Sometimes, while working with Python Strings, we have problem in which we need to perform a case conversion of String. This a very common problem. This can have application in many domains such as web development. Lets discuss certain ways in which this task can be performed.
Input : geeks_for_geeks
Output : GeeksforGeeksInput : left_index
Output : leftIndex
Method #1 : Using title() + replace()
This task can be solved using combination of above functions. In this, we first convert the underscore to empty string and then title case each word.
# Python3 code to demonstrate working of # Convert Snake case to Pascal case # Using title() + replace() # initializing string test_str = 'geeksforgeeks_is_best' # printing original string print("The original string is : " + test_str) # Convert Snake case to Pascal case # Using title() + replace() res = test_str.replace("_", " ").title().replace(" ", "") # printing result print("The String after changing case : " + str(res)) |
The original string is : geeksforgeeks_is_best The String after changing case : GeeksforgeeksIsBest
Method #2 : Using capwords()
The task of performing title case is performed using capwords() in this method.
# Python3 code to demonstrate working of # Convert Snake case to Pascal case # Using capwords() import string # initializing string test_str = 'geeksforgeeks_is_best' # printing original string print("The original string is : " + test_str) # Convert Snake case to Pascal case # Using capwords() res = string.capwords(test_str.replace("_", " ")).replace(" ", "") # printing result print("The String after changing case : " + str(res)) |
The original string is : geeksforgeeks_is_best The String after changing case : GeeksforgeeksIsBest
