如何使用python从一个大的文本文件创建5个小的文本文件

Question

假设我有一个大文件名input.txt，其中包含10行文本：

Lorem Ipsum is simply a dummy text of the printing and typesetting
industry. Lorem Ipsum has been the industry's standard dummy text ever
since the 1500s  when an unknown printer took a galley of type and

remaining essentially unchanged. It was popularised in  the 1960s with
the release of Letraset sheets containing Lorem Ipsum passages,  and

我想创建5个文本文件，每个文件包含2行。类似这样的东西：

./first.txt
Lorem Ipsum is simply a dummy text of the printing and typesetting

Answer 1

这是脚本：

file = open('input.txt', 'r', encoding="utf-8")
Lines = file.readlines()  
count = 0
i = 0
string = []
for line in Lines:
#     print(line)
if(count == 2):
write_file = open(str('input') + str(i) + '.txt', 'w', encoding="utf-8")
write_file.writelines(string)
string = []
i += 1
count = 0
else:
string.append(line)
count += 1

是一种通用方法

with open('input.txt', 'r', encoding="utf-8") as fic:
lines = fic.readlines()
# number of lines per file
split_size = 2
for idx in range(len(lines) // split_size):
with open(f"input{idx}.txt", 'w', encoding="utf-8") as fic:
fic.writelines(lines[idx * split_size:(idx + 1) * split_size])
