如何使用python计算csv文件中单词的出现次数？

Question

So for my assignment I was giving a csv file and am supposed to print the number of people in the file, the amount of each type of email (.jp , .uk., etc.) and print the last names in the file that show up more than once. Whenever I run the program, it says there is 0 of each email type. What am I doing wrong?

I thought by using 'if " " in file" it would find each one and add it to "jp". Any suggestions?

inFile = open('mydata.csv', 'r')

i = 0
jp = 0
uk = 0
de = 0

for line in inFile:
    i = i + 1
````
if '.jp' in inFile:
    jp = jp + 1
````
if '.uk' in inFile:
    uk = uk + 1
````
if '.de' in inFile:
    de = de + 1

print('There are', i - 1,'people in this file,')
print('There are', jp,'emails that end in .jp')
print('There are', uk,'emails that end in .uk')
print('There are', de,'emails that end in .de')

inFile.close()
outFile.close()

You aren't iterating across the contents of the file for your if conditions.

for line in file:
   i = i + 1
   if '.jp' in line:
       ...
   if '.uk' in line:
       ...
