问题 I want to read an array of integers from single line of input in python3. For example: Read this array to a variable/list 1 3 5 7 9 What I have tried arr = input.split(' ') But this does not convert them to integers.

问题 I'm trying to send a group of files to a remote server through no-ack's python byndings for libssh2, but I am totally lost regarding the library usage due to the lack of documentation. I've tried using the C docs for libssh2 unsuccesfully. Since I'm using python 3.2, paramiko and pexpect are out of the question. Anyone can help?
