Split func error

Question

This code I wrote generates an error :

words = input().lower().split(',')

print(words)

for x in words.split(): #error: “list “ object had no function split
print(x)

When this code generates no error and runs good:

words, pattern = input().lower().split(',')

words = [i.strip() for i in words.split()] # here is the same
pattern = pattern.strip()

print("Word '{}' appear {} time(s)".format(pattern, words.count(pattern))

I don’t understand that. When some can help me I would be cool.

Answer 1

firstly, it would be much more helpful if you made a code in playground so others can access it right away and see the issue firsthand (instead of pasting it here....)

now for your issue:
first, you take input, lowercase it and split it, and then assign it into words

your issue arise when you attempt this line:
for x in words.split():

words is a list at this point

a list does not have a split function, therefore the error

simply remove the ".split()" from that line and it should run

Answer 2

as i stated, in the mywords code, remove the .split() from the line

for x in words.split():

as for the other code, you still got an issue there (it will only work for pairs of words seperated by "," ex. hello,world)

Answer 3

I published this two files. You can look inside. Why I one example that works and in another not?

Answer 4

Yes the “,” separates the inputs. When you make more “,” than once the program will be confused .
But the expression: i.strip() for i in words.split() don’t cause the error and in the another code it does. I just don’t understand why . I have another one published as word1. Make no issue too.
Besides there is no answer for all questions ;)
