Python字符串切片

Question

代码:

count = 0
oldcount = 0
for char in inwords:
    if char == " ":
        anagramlist.append(inwords[oldcount, count])
        oldcount = count
        count = 0
    else:
        count += 1

错误:

Traceback (most recent call last):
  File "C:/Users/Knowhaw/Desktop/Python Programs/Anagram solver/HTS anagram.py", line 14,        
in <module>
    anagramlist.append(inwords[oldcount, count])
TypeError: string indices must be integers

这到底是怎么回事？count和oldcount显然是整数,但错误说它们不是

我甚至可以写

anagramlist.append(inwords[int(oldcount), int(count)])

并得到相同的错误

Answer 1

您正尝试将其(oldcount, count)用作列表的索引.这是一个元组,而不是int.

你或许是这样的意思:

anagramlist.append(inwords[oldcount:count])

？
