[正則]借人氣求一個(gè)python正則

ghostvic

要用Python從一個(gè)很長(zhǎng)的串中提取一些字串（它們都以/jobs?viewJob=&jobId=開(kāi)始，以%3Aprimary結(jié)束），

多謝了，各位

   我試了下，不知道為啥不行，我啥地方寫(xiě)錯(cuò)了么？
foundURL = re.findall(r'(?<=/jobs?viewJob)(.*)?(?=%3Aprimary)',data)

謝謝

自己搞出來(lái)了，
foundURL = re.findall(r'\/jobs\?viewJob.*?%3Aprimary',data)

但是用(?<=right_text)(.*)?(?=left_text) 總報(bào)錯(cuò)

    這個(gè)可以 將第二個(gè)?使用反斜線轉(zhuǎn)義，把第三個(gè)?放到括號(hào)里面 foundURL = re.findall(r'(?<=/jobs\?viewJob)(.*?)(?=%3Aprimary)',data)

另外 這個(gè)正則匹配到的字符串是不包含/jobs?viewJob以及%3Aprimary頭尾的，只會(huì)獲得頭尾之間的字符串。

1. re.findall(r'\/jobs\?viewJob=(.*)%3Aprimary',url)
