dict - Ralat semasa menulis dic ke txt dalam Python: objek seperti bait diperlukan, bukan 'str'

Question

 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
<class 'str'>

Traceback (panggilan terbaharu terakhir):
Fail "/Users/Air/itchat/test.py", baris 8, dalam <modul>

output.write(write_str)

TypeError: objek seperti bait diperlukan, bukan 'str'

Answer 1

Tukar cara buka kepada w, jangan guna wb. b bermaksud binari

Answer 2

用wb打开，需要encode

`dic = {2:'bob',3:'alice'}
output = open('/Users/Air/itchat/push.txt','wb')
untuk saya dalam dic:

print (i,dic[i])
write_str = str(i) + ' ' + str(dic[i]) + '\n'
print(type(write_str))
output.write(write_str.encode())

output.close()`
