Question

我需要在Python中打开的txt文件中的' * START'和'* END'之前省略所有信息（因此.txt只是正文）我们得到了一个字符串参数并写了。它继续写出原始的.txt而不仅仅是正文

def copy_file_2(s:str):

“如果它的参数是'Gutenberg trim'，它将只复制Project Gutenberg文件的正文，省略前面和后面的”housekeeping“材料。”

infile_name = input("Please enter the name of the file to copy: ")
infile = open(infile_name, 'r', errors = 'ignore')
outfile_name = input("Please enter the name of the new copy:  ")
outfile = open(outfile_name, 'w')

if s == 'Gutenberg trim':
    infile_data = infile.readlines()
    for i in range(len(infile_data)):
        t = '{:5d}: {}'.format(i+1,infile_data[i])
        if "*** START" in t:
            outfile.write(t)
else:
    for line in infile:
        outfile.write(line)  
infile.close()
outfile.close()

Answer 1

print re.search("START(.*)END",open("some_file").read(),re.DOTALL).groups()[0]

我很确定你应该可以正常工作......
