[Python] How do I perform a function A set number of times and countdown each time it is...

I've created a time calculator to tell a user their time spent in flight.

I've figured out how to create these functions and call them however I'm not sure how to repeat a function again. In this case if the user specifies multiple flights were performed I'd need to repeatedly ask the user for the information for each flight. I think this should be performed by a function that executes a number of times specified by the user or some kind of loop that adds a previous total to a new total.

But how do I write this code?

Do I have to assign a new value for every instance the user enters a new time?

How do I store previous times to add to a new time?

Here is the code:

#Function that calculates time accumulated.
def time_calc(take,land) :
#Take off and landing time is split into two pieces.
Tk =take[:2]
Tk2 = take[2:]
Ld = land[:2]
Ld2 = land[2:]

#The pieces of take off and landing time is converted into integers to perform math.
int(Tk)
int(Tk2)
int(Ld)
int(Ld2)

#Conditions are created in order to calculate remaining time
if Ld2 < Tk2:
Lda = int(Ld) - 1
Ld2 = 60

Flight_time1 = int(Lda) - int(Tk)
Flight_time2 = int(Ld2) - int(Tk2)

#Final value is returned
x = Flight_time1, "Hours", Flight_time2, "Minutes"
return x

else:
Flight_time1 = int(Ld) - int(Tk)
Flight_time2 = int(Ld2) - int(Tk2)

#Final value is returned
x = Flight_time1, "Hours", Flight_time2, "Minutes"
return x

#Initial function to receive input from the user and call on the calculator function to perform math

def flight_form():
Take_off1 = input ("Please enter take off time:")
Landing1 = input ("Please enter Landing time:")
Mult = input ("Was there multiple flights?(True or False)")

take = Take_off1
land = Landing1
bool(Mult)

if Mult == True:
flight_number = input ("How many?")
int(flight_number)

x = time_calc(take,land)
print (x)
else:
x = time_calc(take,land)
print (x)

flight_form()


I was thinking of using a for loop. E.g, for flight_number() something perform this function x amount of times.

I'm unsure how to write this in code.
