Given a snake case string, convert to camel case.
Input : test_str = ‘geeksforgeeks_is_best_for_geeks’
Output : geeksforgeeksIsBestForGeeks
Explanation : String converted to Camel Case.Input : test_str = ‘geeksforgeeks_best_for_geeks’
Output : geeksforgeeksBestForGeeks
Explanation : String converted to Camel Case.
Method #1 : Using split() + join() + title() + generator expression
The combination of above functions can be used to solve this problem. In this, we first split all underscores, and then join the string appending initial word, followed by title cased words using generator expression and title().
Python3
# Python3 code to demonstrate working of # Convert Snake Case String to Camel Case # Using split() + join() + title() + generator expression # initializing string test_str = 'geeksforgeeks_is_best' # printing original string print("The original string is : " + str(test_str)) # split underscore using split temp = test_str.split('_') # joining result res = temp[0] + ''.join(ele.title() for ele in temp[1:]) # printing result print("The camel case string is : " + str(res)) |
The original string is : geeksforgeeks_is_best The camel case string is : geeksforgeeksIsBest
Method #2 : Using split() + join() + title() + map()
The combination of above functions can be used to solve this problem. In this, we perform the task of extending logic to entire strings using map().
Python3
# Python3 code to demonstrate working of # Convert Snake Case String to Camel Case # Using split() + join() + title() + map() # initializing string test_str = 'geeksforgeeks_is_best' # printing original string print("The original string is : " + str(test_str)) # saving first and rest using split() init, *temp = test_str.split('_') # using map() to get all words other than 1st # and titlecasing them res = ''.join([init.lower(), *map(str.title, temp)]) # printing result print("The camel case string is : " + str(res)) |
The original string is : geeksforgeeks_is_best The camel case string is : geeksforgeeksIsBest
