why does this give me an error?

Question

txt = input()

list = txt.split()

var = 0

for word in list:
if len(word) > var:
var = word

print(var)

Answer 1

It will still throw errors for most inputs.
var = word means that you again assign a string to var which will cause an error in the next iteration.

Answer 2

Var is a string, so the comparison with len(word) makes no sense and will throw an error. Use
var = 0
instead.

Answer 3

A tip for the future: using descriptive variable names makes mistakes like this less likely. E.g. instead of "var" you could use "max_length". That way it's immediately obvious that assigning a word to it makes no sense.

Answer 4

this works!

Answer 5

i was trying to print the longest word

Answer 6

txt = input()

list = txt.split()

var = 0

for word in list:
if len(word) > var:
var = len(word)

for word in list:
if len(word) == var:
print(word)
