文件处理、字典和地图

Question

所以我应该按照这种格式来查找文本文件的出现次数。但我的代码可能是完全错误的。text = open('text3.txt','r')d = dict()fname = input('Enter the file name:')l = input('Enter letter to be searched:')k = 0with open(fname, 'r') as f:    for line in f:        words = line.split()        for i in words:            for letter in i:                if(letter == 1):                    k = k+1print('Occurences of the letter:')print(k)有人可以帮我吗？

是的，您可以改为迭代字符：

fname = input('Enter the file name:')

char = input('Enter letter to be searched:')

i = 0

with open(fname, 'r') as f:

  data = f.read()

  for each in data:

    if each == char:

      i += 1

print(i)
