如何打开输入文件，对其进行编辑，然后使用python以其他名称保存

我想打开一个名为file1.txt的文本文件，计算长度，然后用file2.txt关闭它

我非常不喜欢进口任何东西

file1 = open('file1.txt')
def wordCount(file1):
    contents = file1.read()
    file1.close()
    print(contents)
    return len(contents)
print(wordCount(file1))

结果是应该的，但我不知道下一步该从哪里开始。

这里是：

    file1 = open('file1.txt')
    def wordCount(file1):
        contents = file1.read()
        file2=open('file2.txt','w')
        file2.write(contents)
        file2.close()
        file1.close()
        print(contents)
        return len(contents)
    print(wordCount(file1))

因此，是否要将

file1.txt

更改为

file2.txt

？如果要在file2中包含长度，则可能会重复？请使用file2。打开后写入（“您的内容”）

# Copying then editing files
local_saved = []
with open("file1.txt", "r") as f:
    local_saved.append(f.read())

with open("file2.txt", "w+") as f:
    text_to_write = local_saved[0]
    # Edit text_to_write below. 
    # Can be deleted (text_to_write = "") or changed in any way as if it were a normal string.
    # ...

    f.write(text_to_write)
