如何将输出保存到新的文本文件中？

Question

基本上，我有一个超长的输出，我希望能够将这个输出保存到一个全新的文本文件中，而不需要更改我的旧文件。到目前为止，这是我的代码，我基本上只需要知道如何处理我的out_file变量。

感谢所有未来的帮助。

txt_list = []

with open("X:\- Photogrammetry\Python to Correct DXF Colors\InvolvedPontiac.dxf", "r") as in_file, open("X:\- Photogrammetry\Python to Correct DXF Colors\InvolvedPontiacfixed.txt", "w+") as new_file:
    for line in in_file:
        line = line.rstrip()
        txt_list.append(line)
Entity = 0
i = 0
while i < len(txt_list):
    if txt_list[i] == "ENTITIES":
        Entity = 1
    if txt_list[i] == " 62" and Entity == 1:
        txt_list[i+1] = " 256"
    i += 1


Layer = 0
j = 0
while j < len(txt_list):
    if txt_list[j] == "LAYER" and txt_list[j+2] != " 7":
        Userinput = input("What color would you like for the layer " +txt_list[j+2] + "? Type 0 for black, 1 for red, 3 for green, 4 for light blue, 5 for blue, 6 for magenta, 7 for white, 8 for dark grey, 9 for medium gray, or 30 for orange.")
        txt_list[j+6] = " " + Userinput

        print ("The " + txt_list[j+2] + " layer now has a color code of " + Userinput)
    j += 1
for item in txt_list:
    new_file.write(item)
print ('\n'.join(txt_list))

我不知道你的代码到底是怎么回事。

但是要将变量写入文件，可以使用

with open('output.txt', 'w+') as new_file:
    new_file.write(variable)

请注意，如果文件不存在，'w+'将创建该文件，如果它存在，则会覆盖它。

如果是txt_list中想要写入该文件的所有项目，我不认为我会首先对它们进行join。只需使用for循环：

with open('output.txt', 'w+') as new_file:
    for item in txt_list:
        new_file.write(item) 

这将在文件中的新行中打印该列表中的每一项。

txt_list = []

with open("X:\- Photogrammetry\Python to Correct DXF Colors\InvolvedPontiac.dxf", "r") as in_file:
    for line in in_file:
        line = line.rstrip()
        txt_list.append(line)
Entity = 0
i = 0
while i < len(txt_list):
    if txt_list[i] == "ENTITIES":
        Entity = 1
    if txt_list[i] == " 62" and Entity == 1:
        txt_list[i+1] = " 256"
    i += 1


Layer = 0
j = 0
while j < len(txt_list):
    if txt_list[j] == "LAYER" and txt_list[j+2] != " 7":
        Userinput = input("What color would you like for the layer " +txt_list[j+2] + "? Type 0 for black, 1 for red, 3 for green, 4 for light blue, 5 for blue, 6 for magenta, 7 for white, 8 for dark grey, 9 for medium gray, or 30 for orange.")
        txt_list[j+6] = " " + Userinput

        print ("The " + txt_list[j+2] + " layer now has a color code of " + Userinput)
    j += 1

with open('output.txt', 'w+') as new_file:
    for item in txt_list:
        new_file.write(item)

print ('\n'.join(txt_list)
