How ro check a longest wors in a file

Question

file handling

Answer 1

with open("file.txt", "w") as f:
f.write("Hello World Helo Wrld")

def f1(words):
return max(words, key=len)

def f2(words):
m = len(max(words, key=len))
return [i for i in words if len(i)==m]

with open("file.txt") as f:
words = f.read().split()
print(f1(words))
print(f2(words))

Answer 2

If you have a file, remove first "with" and replace second with
f = open( filename )
words = f.read().split()
print(f1(words))
print(f2(words))
f.close()

Answer 3

f1 finds max item in iterable using len function for comparing
f2 finds length of longest word and returns a list containing items with same length
