我是 python 的新手，這個錯誤不斷出現

Question

錯誤 ：

traceback (most recent call last):   file "main.py", line 6, in <module>
    states_in_india [0] = "Rajastan" typeerror : 'tuiple' object does not support item assignment

編碼 ：

states_in_india = "Maharashtra","Gujrat","Punjab"

print(states_in_india)

states_in_india[0] = "Rajastan"

states_in_india.extend = "Tamilnadu"

print (states_in_india)

Answer 1

元組是不可變的，因此您不能通過為它們的索引之一分配值來改變它們。

您可能想要使用列表。

states_in_india = "Maharashtra","Gujrat","Punjab"
states_in_india[0] = "whatever" #illegal

states_in_india = ["Maharashtra","Gujrat","Punjab"]
states_in_india[0] = "whatever" #legal, changes the list
states_in_india
>>> ["whatever","Gujrat","Punjab"]

Answer 2

states_in_india = "Maharashtra","Gujrat","Punjab" # this is tuple

print(states_in_india)
# below line is illegal in tuple cause you can't add, remove from tuple 
states_in_india[0] = "Rajastan"

將您的代碼轉換為列表

    states_in_india = ["Maharashtra","Gujrat","Punjab"]

在您的代碼中添加 [] 將聲明為列​​表

states_in_india[0] = "Rajastan"

此代碼將完美地工作
