You can’t treat arrays of digits as a single number. The easiest way to read a numeric string is to use the sys library to read a line from the keyboard.

import sys
print(“Enter value for mass”)
mass = sys.stdin.readline()
mass = float(mass)

If you really want to read one digit at a time, you can use a string variable in place of an array.

mass= ””
num=“0”
while num.isdigit():
...mass += num
...num= input(“Enter mass value”)

mass=float(mass)
