python打印到文件可以在控制台中正确打印，但不能在文件中打印

Question

Being new to python unfortunately I get stuck on rather trivial things. I am trying to print a dictionary to file. Dict entries look like:

{'a': array(['a', 'b', 'c', '123.d', 'lalal.fufu'], dtype=object)}

I am using python write to file from dictionary answer to do the printing, as

for (name, mobile) in Dict.iteritems():
    with open('C:\dir\file.csv', "a") as f:
        print ('A %s gives B %s \n' % (name, str(mobile)))
        f.write(name)
        f.write(mobile)
f.close()

but for some reason i get the output in console window (correctly) but the file contains gibberish in the mobile part. It's like the mobile is not converted to string despite casting of str(). Haven't found any similar case in answered questions :=(

Help please?

Thanks!

Answer 1

You did cast your object to a string in the console line:

print ('A %s gives B %s \n' % (name, str(mobile)))

But you forgot to do it in the f.write method:

f.write(mobile)

It should be:

f.write(str(mobile))
