[英]Writing a Python Function that returns a list of the most common words in a text file?
我有點難以弄清楚這一點。 此功能應該執行以下/遵守以下准則:
def mostCommonWords(filename, N):
return "stub"
- Read the file from filename in your function and returns a dictionary
with the frequency of each word as its value.
- Words are separated by whitespace characters, but do not include
the following punctuation characters (,.!?;). You can assume contractions
count as one word (i.e. "don't", "you'll", etc. are one word).
- The split and strip functions may be useful.
- You can assume contractions count as one word
(i.e. "don't", "you'll", etc. are one word).
- Your function should open the file for reading, and close
the file before returning.
我已經完成了輔助功能:
def wordFrequency(filename):
frequency = {}
file = open(filename, 'r')
for line in file.readlines():
for word in line.strip().split():
if word not in frequency:
frequency[word] = 0
frequency[word] += 1
file.close()
return frequency
但是,我不確定如何從這里開始。 有人可以提供一些指導嗎?
我想下一步是學習如何將結果從高到低排序,然后決定一種向用戶表示此信息的方式。 可能最簡單的方法是打印它。
我猜 N 參數旨在限制您打印的值(字)數量?
