统计字符串、字符个数

str.count(substr, start, end)

filepath = '/Users/qufang01/test/a1.sh'
handle = open(filepath, 'r')
chinanum = 0
wordnum = 0
line = handle.readline()
while line:
    linelen = len(line)
    chinanum = chinanum + line.count('成语', 0, linelen)
    wordnum = wordnum + line.count('hello', 0, linelen)
    line = handle.readline()
print('chinanum:', chinanum)
print('wordnum', wordnum)
