Hello,guys.I know that this page might no talking about HardWare,please dont report me,thanks a lot.

Well,recently i had to learn a Python third party libraries which BeautifulSoup(Does it really taste good?),and now here is a project(actually is a homework yet),need me to Statistics  how many times of each name has appear in this html page.

Here is my way:contract all name into a txt files,and use split() and dictionary to make it,but here is a thing that when i try to contract this BS moudle into a txt files,it only appear one name!! Where is my fault?Please point for me if you are studying Python now or you are a Python Worker or Master on it.

Thanks a Lot.

You should write to the file inside the for loop. The way you're doing you're just saving the remaining garbage in the span variable.

Doing something like that should do the trick:

f=open('catch.txt','a')
for span in name:
    print(span.string)
    f.write(span.string)
    f.write('\n')

d=[]
for word in lis:
    if lis not in word:
        d[lis]=1
    else:
        d[lis]+=1
print(d)

That is totaly what i write,but it says unreaddable in my VisualStudio yet.

You can do something like this. You can either use f.seek(0) to return back to the beginning of the file instead of closing and reopening if you want. Make sure you close the file after you're done reading it though.

 

Also, you could use a Counter instead of writing to a file (or just count the names from the "name" array the way you are currently doing it).

Well,why you make a close options upon open command?
