从文本文件创建Python字典并检索每个单词的计数

Question

我试图从文本文件中创建一个单词字典，然后计算每个单词的实例，并能够在字典中搜索单词并接收其计数，但我处于停顿状态。我有最大的困难，使文本文件字小写和删除他们的标点符号，因为否则我的计数将关闭。有什么建议吗？

f=open("C:\Users\Mark\Desktop\jefferson.txt","r")
wc={}
words = f.read().split()
count = 0
i = 0
for line in f: count += len(line.split())
for w in words: if i < count: words[i].translate(None, string.punctuation).lower() i += 1 else: i += 1 print words
for w in words: if w not in wc: wc[w] = 1 else: wc[w] += 1
print wc['states']

Answer 1

File_Name = 'file.txt'
counterDict={}

with open(File_Name,'r') as fh:
    for line in fh:
   # removing their punctuation
        words = line.replace('.','').replace('\'','').replace(',','').lower().split()
        for word in words:
            if word not in counterDict:
                counterDict[word] = 1
            else:
                counterDict[word] = counterDict[word] + 1

print('Count of the word > common< :: ',  counterDict.get('common',0))
