dic = {2:'bob',3:'alice'}
output = open('/Users/Air/itchat/push.txt','wb')
for i in dic:
print (i,dic[i])
write_str = str(i) + ' ' + str(dic[i]) + '\n'
print(type(write_str))
output.write(write_str)
output.close()
PyCharm运行报错如下：
2 bob

Tukar cara buka kepada w, jangan guna wb. b bermaksud binari
用wb打开，需要encode
`dic = {2:'bob',3:'alice'}
output = open('/Users/Air/itchat/push.txt','wb')
untuk saya dalam dic:
output.close()`
