Another reason why for loops are useful

[leavesntwigs]

In the section about for loops ...
"One way to print each character is to use four print statements:
print(word[0])
print(word[1])
print(word[2])
print(word[3])

...
This is a bad approach for two reasons:"

Another reason why this is a bad approach is for maintenance. If we wanted to print each letter followed by a comma, for example, we would have to change four lines of code. If we have a for loop, with a single print(word[I]) then we need only change one line of code.
