Hi all, i could use a little help with this one, i'm supposed to be calculating decay rates using specifically trinket but i'm having trouble with line 23 of my code, namely i'm getting a tuple/float error. "TypeError: unsupported operand type(s) for Div: 'list' and 'float' on line 23 in main.py" - from math import *
-
import numpy as np
-
from numpy import array
-
import matplotlib.pyplot as plt
-
-
x = 1
-
-
time = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35]

while True:
-
name = input ("Enter name of isotope or type End to finish")
-
if name == "End":
-
break
-
else:
-
tau = float(input("Enter half-life of named isotope in seconds"))
-
m = float(input("Enter starting mass of isotope in grams"))
-
T = float(input("Enter time elapsed in seconds"))
-
y = m * (exp((-log(2)) * (T / tau)))
-
print "Mass of remaining isotope is", y, "g"
-
Start = 5 / (exp((-log(2)) * (30 / tau)))
-
print "To have 5 grams remaining after 30 s we need a starting mass of", Start, "g"
-
-
n = m * (exp((-log(2)) * (time / tau)))
-
-
plt.plot(t,n)
-
plt.title("Radioactive decay rates of isotopes")
-
plt.xlabel("Time / s")
-
plt.ylabel("Remaining mass / g")
-
plt.show()
