why does the dictionary key not update to record the change in keys-CodePudding

the goal is to increase the dictionary key by 1 so all values generated by for loop are stored in a dictionary

code

counting = {}
numbers = 1


for i in range(1, 11):
    counting[numbers] = (i)
    numbers   1

print(counting)

but in the final result the dictionary only has one key and one stored value that is

result of running the code {1: 10}

how do i make it that the keys changes with each loop and stores all the values generated

You have to put numbers = 1 or numbers = numbers 1 instead of numbers 1 if you want to update the variable.

When python sees numbers 1, it just evaluates that line, gets 2, and does nothing with that value. If you don't have an = sign, the variable will not be changed.

I don't think you realize, but there's a silly typo in your code. After assigning the value to dictionary, you increasing the count of numbers, but not assigning it. So, just use = assignment operator.

counting = {}
numbers = 1


for i in range(1, 11):
    counting[numbers] = (i)
    numbers  = 1

print(counting)

O/P:

{1: 1, 2: 2, 3: 3, 4: 4, 5: 5, 6: 6, 7: 7, 8: 8, 9: 9, 10: 10}
