我想将字符串拆分为3个不同的文件（file2、file3和file4）

文件2在字符串中只包含重复的短语

文件3将包含非重复字符串，但不包含整数/数字

文件4将只包含整数/数字

我已经写了下面的代码。该代码对文件2正常工作，但对文件3和文件4无效 我需要帮助，了解如何编写适用于file3和file4的代码

file1 = open("file1.txt", "rt")
file2 = open("file2.txt", "wt")
file3 = open("file3.txt", "wt")
file4 = open("file4.txt", "wt")

content = file1.readlines()
repeat = "Happy Easter Holidays"
print("Processing inputs")

for line in content:
    if repeat in line:
        file2.write(line)
    if repeat not in line:
        file3.write(line)
    if line.isdigit():
        file4.write(line)

file2.close()
file3.close()
file4.close()

print("Output complete")

Answer 1

在读取文件内容时，python会在每行末尾添加换行符，因此isnumeric（）不起作用

file1 = open("file1.txt", "rt")
file2 = open("file2.txt", "wt")
file3 = open("file3.txt", "wt")
file4 = open("file4.txt", "wt")

def remove_newlines(fname):
    flist = open(fname).readlines()
    return [s.rstrip('\n') for s in flist]

content=remove_newlines("file1.txt")
repeat = "Happy Easter Holidays"
print("Processing inputs")

for line in content:
    if repeat in line:
        file2.write(line+"\n")
    elif line.isnumeric():
        file4.write(line+"\n")
    else:
        file3.write(line+"\n")

file2.close()
file3.close()
file4.close()

print("Output complete")

这里我添加了一个函数，在读取内容时删除换行符
