Attribute Error: list object has no attribute 'apply'

Question

time_weight = list(100*np.exp(np.linspace(-1/divisor, -(num_steps-1)/divisor, num_steps))).apply(lambda x:int(x))

When I try this, I get the following error in Python 3.7.

AttributeError: 'list' object has no attribute 'apply'

Can anyone help with this?

Answer 1

As the error said, list type has no apply attribute. This said, if you have a list l and you want to set to int type every element in it you may use:

l = [int(x) for x in l]

or

l = list(map(int,l))

Answer 2

As the error suggests, list has no apply method. If what you want to do is convert every element to an int, you could remove the lambda function and instead use astype(int):

time_weight = list((100*np.exp(np.linspace(-1/divisor, -(num_steps-1)/divisor, num_steps))).astype(int))
