查找字符串中出现的所有字符 [英] Find all the occurrences of a character in a string

问题描述

我试图找到所有出现的|"在一个字符串中.

I am trying to find all the occurences of "|" in a string.

def findSectionOffsets(text):
    startingPos = 0
    endPos = len(text)

    for position in text.find("|",startingPos, endPos):
        print position
        endPos = position

但我收到一个错误:

    for position in text.find("|",startingPos, endPos):
TypeError: 'int' object is not iterable

推荐答案

功能:

def findOccurrences(s, ch):
    return [i for i, letter in enumerate(s) if letter == ch]


findOccurrences(yourString, '|')

将返回|出现的yourString的索引列表.

will return a list of the indices of yourString in which the | occur.
