使用 python 解析文件中的数据

Question

我有两个文件，一个是模板文件，另一个是包含模板文件值的文件。我试图获取模板文件，然后将值从另一个文件传递给变量，并将这两个文件合并到第三个文件中。我可以使用以下代码片段将一个文件复制到另一个文件 `

print("Enter the Name of Source File: ")
sFile = input()
print("Enter the Name of Target File: ")
tFile = input()
fileHandle = open(sFile, "r")
texts = fileHandle.readlines()
fileHandle.close()

fileHandle = open(tFile, "w")
for s in texts:
    fileHandle.write(s)
fileHandle.close()

print("\nFile Copied Successfully!")

`

但是我不知道如何对两个或多个文件执行此操作，然后将它们制作成一个文件。任何帮助/指导表示赞赏

这当然不是最优雅的解决方案，但我认为它应该适合您。

# You could add as many files to this list as you want.
list_of_files = []

count = 1
while True:

    print(f"Enter the Name of Source File{count} (Enter blank when done adding files): ")
    sFile = input()
    # If the input is not empty then add the filename to list_of_files.
    if sFile:
        list_of_files.append(sFile)
        count += 1
    else:
        break

print("Enter the Name of Target File: ")
tFile = input()

# With open will open the file and then close if when done.
with open(tFile, 'a+') as target:
    # This will loop over all the files in your list. 
    for file in list_of_files:
        tmp = open(file, 'r')
        target.write('\n' + tmp.read())
        tmp.close()
