You can read the content of each file directly into the write method of the output file handle like this:
您可以像这样直接将每个文件的内容读入输出文件句柄的 write 方法中：
import glob
read_files = glob.glob("*.txt")
with open("result.txt", "wb") as outfile:
for f in read_files:
with open(f, "rb") as infile:
outfile.write(infile.read())

You could try something like this:
你可以尝试这样的事情：
import glob
files = glob.glob( '*.txt' )
with open( 'result.txt', 'w' ) as result:
for file_ in files:
for line in open( file_, 'r' ):
result.write( line )
Should be straight forward to read.
应该直接阅读。

The fileinputmodule is designed perfectly for this use case.
该fileinput模块专为此用例而设计。
import fileinput
import glob
file_list = glob.glob("*.txt")
with open('result.txt', 'w') as file:
input_lines = fileinput.input(file_list)
file.writelines(input_lines)

filenames = ['resultsone.txt', 'resultstwo.txt']
with open('resultsthree', 'w') as outfile:
for fname in filenames:
with open(fname) as infile:
for line in infile:
outfile.write(line)

It is also possible to combine files by incorporating OS commands. Example:
还可以通过合并操作系统命令来组合文件。例子：
import os
import subprocess
subprocess.call("cat *.csv > /path/outputs.csv")
