Traversing a string
Traversing just means to process every character in a string, usually from left end to right end
Python allows for 2 ways to do this – both useful but not identical
if all you need is the value of each character in the string
for
ch
in
stringvar
:
will work fine.
ch
is given the value of each character from left to right, and can be used
in the for loop as you need
The other way uses the
location
of the characters in the string
for
ct
in range(len(
stringvar
)):
makes the variable
ct
an integer which has all the values of the subscripts of the
characters in the string. If it is important that you know
where
a character is, this
is the form you use.
