[問題] 關於重複搜尋

[paulluopaull (ppoo)]

小弟最近在做PYTHON習題

Problem

Given: A string ss of length at most 10000 letters.

Return: The number of occurrences of each word in ss, where words are
separated by spaces. Words are case-sensitive, and the lines in the output
can be in any order.

Sample Dataset:

We tried list and we tried dicts also we tried Zen


Sample Output:

and 1
We 1
tried 3
dicts 1
list 1
we 2
also 1
Zen 1

但是小弟做同樣練習時會重複出現有重複的字:
we 3 -------1st occured
tried 3-------1st occured
list 1
and 1
we 3-------2nd occured
tried 3-------2nd occured
dicts 1
also 1
we 3------3rd occured
tried 3------3rd occured
zen 1

以下為小弟的CODE，再請各位大大幫忙檢視一下問題出在哪裡了。謝謝!

lines = 'We tried list and we tried dicts also we tried Zen'
for word in lines.lower().split(' '):
    pare = {word: lines.lower().count(word)}
    pare.update(pare)   #希望用update消除重複項
    for k1, v1 in pare.items():
        print(k1, v1)

→ wennie0433: word那個回圈每次都會重製你的pare所以根本沒紀錄到
→ wennie0433: 迴圈外面宣告一個dup = dict()
→ wennie0433: 然後dup.update(pare)
→ wennie0433: 最後那個迴圈就直接搬出來不要在迴圈裡面pare換成dup
→ wennie0433: 然後他題目大小寫應該市分開算lower()要拿掉
→ zerof: {k: lines.count(k) for k in set(lines.split())}
