获取从一个文本到另一个文本文件的值

Question

如何将一个文本的值追加到另一个文本文件中的特定位置？

One.txt

date : 26/04
test_name : Cs
link1 : xyz
link2 : abc

Second.txt

Pending of taking test {test_name} was due on {date}. Follow the below link
                               
X_link : {link1} --> replace with xyz from one.txt

y_link : {link2} --> replace with abc from one.txt

需要将second.txt中的one.txt值放置在{}中提到的名称所在的位置。

输出：

Pending of taking test Cs was due on 26/04. Follow the below link
                               
X_link : xyz

y_link : abc

Answer 1

使用正则表达式：

例：

import re

# file_one.read()
one = """date : 26/04
test_name : Cs
link1 : xyz
link2 : abc"""

# file_second.read()    
second = """Pending of taking test {test_name} was due on {date}. Follow the below link
X_link : {link1} --> replace with xyz from one.txt
y_link : {link2} --> replace with abc from one.txt"""

for k, v in re.findall(r"(\w+)\s*:\s*(\w+)", one):
    second = re.sub(f"{{{k}}}", v, second)    # substitute value
print(second)

输出：

Pending of taking test Cs was due on 26. Follow the below link
X_link : xyz --> replace with xyz from one.txt
y_link : abc --> replace with abc from one.txt
