如何打印单词直到达到特定单词？

Question

文件1=…blahblahblah\nblah律师Amy\nblahblah…：想打印“艾米律师”

文件2=…\nblahblahblahblah律师艾米（政府）\nblahblah….：想要打印“艾米律师（政府）”

文件3=…等等\nblahblahblah律师艾米、迈克尔、梅西想打印“律师艾米，迈克尔，梅西”

所以我需要打印“律师~before\n”

我怎样才能解决这个问题

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

Answer 1

这里有一个函数，可以满足您的需要。它打开文件并开始打印其行。当一个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

Answer 2

以下是一种正则表达式查找所有方法：

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