The error message “value is not a valid list (type=type_error.list)” indicates that a variable or object is being expected to be a list data type, but the actual value assigned to it is not a list.
Here’s an example to help understand the error better:
value = 10
my_list = value
print(my_list)
In this example, the variable “value” is assigned a value of 10, which is an integer data type. Then, the variable “my_list” is assigned the value of “value”. However, since “value” is not a list, the error occurs when trying to assign it to “my_list”.
To fix this error, you need to make sure that the variable or object assigned to a list is actually a list data type. Here’s an updated example:
value = [1, 2, 3]
my_list = value
print(my_list)
In this updated example, the variable “value” is assigned a list of numbers. Then, the variable “my_list” is assigned the value of “value”, which is a valid list. Now, when you print “my_list”, it will output [1, 2, 3].
