Using python, how would I fix my error?

Write a function named standardize_weight that takes in as input a string and returns an intege
The function will do the following (in the order specified):
1) convert all characters of the string into lowercase
2) strip the string of all leading and trailing whitespace
3) replace any occurences of 'Ibs' with " (remove it from the string)
4) replace any occurences of 'lb' with " (remove it from the string)
5) replace any occurences of 'pounds' with " (remove it from the string)
6) If the string contains the substring 'kg', then:
6.1) replace 'kg' with "
6.2) strip the string of whitespace
6.3) cast the string into a float type using the function float()
6.4) multiply the resulting float by 2.2 (an approximate conversion of kilograms to pounds)
8) try to return the int of your stri
If it cannot, return np.nan .
I # YOUR CODE HERE
def standardize_weight(weight):
weight =
weight = weight.strip()
weight.lower()
weight
weight
weight = weight.replace('pounds', '')
weight.replace('lbs', '')
weight.replace('lb',
%3D
%3D
if 'kg' in weight:
weight
weight
weight = float(weight)
weight = weight * 2.2
weight.replace('kg', '')
weight.strip()
try:
weight = int(string)
return weight
except ValueError:
return np.nan
I assert standardize_weight('34 lbs') == 34
assert standardize_weight('101 kg')
== 222
