Typeerror in python with sum, list and range

Question

Good morning, srs,

Why this result in error?

n = float(input("Origin value : "))
K = float(1)
while K <= n:
   P = sum(list(range((float(K)), float(n*K))))
   K*= 1.05
print(P, "and", K)

In this case appear:

    P = sum(list(range((float(K)), float(n*K))))
TypeError: 'float' object cannot be interpreted as an integer

Thank you, srs!

Answer 1

The range function wants an integer (you can't do something 1.1 times, right?). When you generate your range, decide whether you want to round the bounds up or down.
