python程序告诉没有长度功能的代码中的单词数量？错误是意外的.plzz告诉我哪里错了

Question

i've been trying this code from 1 hour and its output coming out is really unexpected.

var=input('sentence')
no=1
for i in var:
  if i==" ": #i've added a space as the number of words will be the number of spaces in a sentence
    no+=1
print(no)

Answer 1

You forgot the : at the end of your if statement. The following should work:

var=input('sentence')
no=1
for i in var:
  if i==" ":
    no+=1
print(no)
