How to convert value in dictionary from string to int

I have a list of dictionaries, where both the key and value are strings. I am importing the data from a CSV file. The dictionaries look like this:

{'1A': '1',
 '1B': '1',
 '1C': '2'}

I would like to change the values into integers.

I have looked around for a solution but I don't seem to find anything that works.

This is my code (the list is called 'buyers'):

for i in buyers:
    for k, v in i.items():
        i[v] = int(i[v])

I receive this error:

i[v] = int(i[v])

KeyError: '1'

I'm not sure what to do because it says my error is the '1', which seems to me like it should be able to be converted into an int.

You can use list and dict comprehensions.

buyers = [
    {'1A' : '1', '1B' : '1', '1C' : '2'},
    {'2A' : '2', '2B' : '4', '2C' : '3'}
]


result = [
    {key: int(val) for key, val in d.items()}
    for d in buyers
]

print(result)

Output

[{'1A': 1, '1B': 1, '1C': 2}, {'2A': 2, '2B': 4, '2C': 3}]

You need to change i[v] = int(i[v]) to i[k] = int(v)

dict1  = {'1A' : '1', '1B' : '1', '1C' : '2'} 

for k, v in dict1.items():
    dict1[k] = int(v)
print(dict1 )

output:

{'1A': 1, '1B': 1, '1C': 2}
