Strings Built-In Methods

Strings Built-In Methods

In this post I want to show what you can do with the built-in methods for Strings. Let's first create a string with the value of "Hello World"

string = "Hello World"

To manipulate strings, we can use some of Pythons built-in methods

string.upper()   # get all-letters in uppercase

string.lower()    # get all-letters in lowercase

string.capitalize() # capitalize the first letter

string.title()    # capitalize the first letter of words

string.swapcase() # converts uppercase and lowercase

string.strip()    # remove all white spaces

string.lstrip()   # removes white space from left

string.rstrip()   # removes white space from right

string.split()    # splitting words

string.split(',') # split words by comma

string.count('l')   # count how many times l is in the string

string.find('Wo') # find the word Wo in the string

string.index("Wo")  # find the letters Wo in the string

":".join(string)  # add a : between every char

" ".join(string)  # add a white space between every char

len(string)   # find the length of the string
