Python：保存CSV文件

Question

I'm new to python (learning for 2 weeks only) and there's something I really can't even try (I have been googling for an hour and coulndn't find any).

file1 and file2 are both CSV files.

I've got a function that looks like:

def save(file1, file2): 

it is for file2 to have the same content as file1 . For example, when I do:

save(file1, file2)

file2 should have the same content as file1 .

Thanks in advance and sorry for an empty code. Any help would be appreciated!

Answer 1

Python has a standard module shutil which is useful for these sorts of things.

If you need to write the code to do it yourself, simply open two files (the input and the output). Loop over the file object, Reading lines from the input file and write them into the output file.

Answer 2

If you simply want to copy a file you can do this:

def save(file1, file2):
    with open(file1, 'rb') as infile:
        with open(file2, 'wb') as outfile:
            outfile.write(infile.read())

this copies the file with name file1 to the file with name file2 . It really doesn't matter what the content of those files is.
