Python2.7-从tempfile读取

Question

I use python2.7 and i have a question about reading from tempfile. Here is my code:

import tempfile


for i in range(0,10):
    f = tempfile.NamedTemporaryFile()

    f.write("Hello")

    ##f.seek(0)

    print f.read()

With this code , i get something like this:

Rﾜ
nize.pyR
ﾞ`Sc
d
Rﾜ
Rﾜ
Z
Z
nize.pyR
ﾞ`Sc

what are these?

Thanks!

Answer 1

You are writing string to a file opened in bytes mode. Add the mode parameter to your call to NamedTemporaryFile:

f = tempfile.NamedTemporaryFile("w")
