Answer 1

Answer:

import numpy as np

def standardize_weight(inp):

#1

inp=inp.lower()

print(inp)

#2

inp=inp.strip()

print(inp)

#3

inp=inp.replace("lbs"," ")

print(inp)

#4

inp=inp.replace("lb"," ")

print(inp)

#5

inp=inp.replace("pounds"," ")

print(inp)

 

print(inp.find("kg"))

#6

if(inp.find("kg")>=0):

inp=inp.replace("kg"," ")

print(inp)

inp_int=int(inp)

print(inp_int*2)

inp=str(inp_int)

print(inp)

#7

inp=inp.strip()

print(inp)

#8

if(inp.isdigit()):

inp=int(inp)

#9

else:

inp=np.nan

 

res=standardize_weight(" List albkg repLacleg sublkg " )
