无法将浮点数转换为整数

Question

I have a dataset about movies and there's a column that corresponds to each movies' release year. The numbers are currently all floats and I'm trying to convert them to integer.

This is the code I've written to do so:

if isinstance (data['Year'], float):
    for idx, i in enumerate(data['Year']):
        data['Year'][idx]= int(i)
else:
    pass

The code runs. However, whenever i try to print the data type of each element in the column (like:

for i in data['Year]:
print(type(i))

the results I get is still all floats.

Anyone has any idea of why this wouldn't be working? Help would be very much appreciated it!

Answer 1

I think data['Year'] is a list instead of float in your code. Try

data = {'Year': [1990.0, 1991, 2000.0]}

for idx, i in enumerate(data['Year']):
    if isinstance(i, float):
        data['Year'][idx]= int(i)

for i in data['Year']:
    print(type(i))
