Python: Code help

Question

I'm trying to make sure that "getFloat" checks to make sure that a positive value in entered. I tried putting the while loop that is in the code now inside of another while loop that checked for a value>0, but it was ignored. Here is the entire code:

#This is meant to be a simple pace converter for a run/bike activity.
#good practice with def, while, and try/except

#defining funtion to get a number and error-check it
def getFloat(Prompt):
while True:
try:
number=float(input(Prompt))
return number
except ValueError:
print("\nPlease enter a number.")

#Getting inputs from user using "getFloat"
distance = getFloat("How many miles were you active? ")
hours = getFloat("How many hours were you active? ")
minutes = getFloat("How many minutes were you active? ")

#calculations begin here
totalmin=minutes+(60*hours)

x=int(totalmin//distance)
#^made to integer for easier reading in output below
y=(totalmin/distance)%1
#^removes the value of "x" and leaves only the remainder
y*=60
#^multiplying remainder by seconds in a minute
y=round(y,2)
#^cleaning up output by rounding to two decimal places

#output of the answer
print("\nYour pace was",x,":",y,"minutes/mile")

Answer 1

try:
number=float(input(Prompt))
assert number > 0
return number
except (ValueError, AssertionError):
print("\nPlease enter a number.")
