如何打印单词直到到达特定单词？

Question

file1 = ...blahblahblah\nblah律师艾米\n废话....：想打印“律师艾米”

file2 = ...\nblahblahblahblah律师艾米(政府)\nblahblah....：我想打印“律师艾米(政府)”

file3 = ...blah\nblahblahblah律师艾米，迈克尔，梅西\n胡说八道....：想打印“律师艾米，迈克尔，梅西”

所以我需要打印“律师~之前\n”

我该如何解决这个问题？

pseudo code:
f = open(file)
readline = f.readLine()
lawyer = re.findall("Laywer", readline)
print from lawyer till "\n"

Answer 1

下面是一个正则表达式find all方法：

file2 = "\nblahblahblahblah Lawyer Amy(goverment)\nblahblah"
output = re.findall(r'\bLawyer[^\n]+', file2)
print(output)  # ['Lawyer Amy(goverment)']

Answer 2

这里有一个函数可以做你想做的事情。它打开文件并开始打印它的行。当给定的关键字包含在一行中时，它会中断循环。

def print_until(file, keyword):
    with open(file, 'r') as file:
        for line in file.readlines():
            print(line)
            if keyword in line:
                break
