string to list
A string is actually a list of characters. Each element in the string can be accessed with
[] brackets. Yet, if we try to modify a single character, we would fail as Python does not allow that. An error will occur telling TypeError: 'str' object does not support item assignment.We can actually turn a string into a list, where each letter is a separate string in that list. This can be accomplished with
list(). Just like we’ve turned integers to strings with str(), or strings into floats with float(), we can similarly turn a string into a list.fruit = 'apple'
l = list(fruit)
print(fruit) # apple
print(l) # ['a', 'p', 'p', 'l', 'e']
l[1] = '@'
print(l) # ['a', '@', 'p', 'l', 'e']Here, the string
fruit was turned into a list l, which was later modified to contain different characters.Challenge
