Question

use an infinite loop to enter your homework grades of float data type and append them into a list. break the loop when the user enters a grade smaller than 0. create a NUMPY array out of the grades list; create a panda series out of the numpy array and rename the indices to begin from 1 instead of 0(create the new list using list comprehension that begins from 1).

in python

Answer 1

import numpy as np
import pandas as pd
arr=[]
while True:
    grade=float(input("Enter: "))
    if grade<0:
        break
    else:
        arr.append(grade)

arr=np.array(arr)
ser=pd.Series(arr)
idx=[i for i in range(1,len(arr)+1)]
ser.index=idx
print(ser)
