def calculate(s): list = s.split() dict = {} for word in list: if word not in list: dict[word] = 1 else: dict[word] += 1 return dict
if name == 'main': words = "I Like python and you Like java too do you Like python or java" print calculate(words)
报错：Traceback (most recent call last): File "D:/KDR/gg.py", line 15, in <module> print calculate(words) File "D:/KDR/gg.py", line 10, in calculate dict[word] += 1 KeyError: 'I'
