Question

#function to covert kilometer to miles
#takes km input as an argument and return the calculation
def kilometer_to_miles(km):
return km * 0.6214
#function to covert miles to kilometer
#takes miles input as an argument and return the calculation
def miles_to_kilometer(miles):
return miles/0.6214
#Main function to find the distance
#by calling either of the two functions
#prompt the user to enter his/her choice of distance conversion
restart = 0
while (restart == 'y'):
user_input = input ("Enter k to convert kilometer to miles"+ \
"Enter m to converts miles to kilometer: ")
#if statement to execute the user choice of conversion
#Calls the kilometer_to_miles function
if user_input.lower() == 'k':
km = float(input("Enter kilometer to convert to mile: "))
print (km, "makes" ,format(kilometer_to_miles(km),'.2f') , "miles")
#calls the miles_to_kilometer function
elif user_input.lower() == 'm':
miles = float(input("Enter miles to convert to kilometer: "))
print (miles, "miles makes" ,format(miles_to_kilometer(miles),'.2f')
,"kilometer")
#execute if the user's inpupt is none of the above
else:
print("invalid input.")
restart = input ("Enter Y to enter another value and N to quit.")

The problem is it is first printing the restart statement before doing the block under while loop.

Answer 1

Here is code:

#function to covert kilometer to miles

#takes km input as an argument and return the calculation

def kilometer_to_miles(km):

return km * 0.6214

#function to covert miles to kilometer

#takes miles input as an argument and return the calculation

def miles_to_kilometer(miles):

return miles/0.6214

#Main function to find the distance

#by calling either of the two functions

#prompt the user to enter his/her choice of distance conversion

restart = 'y'

while (restart == 'y'):

user_input = input ("Enter k to convert kilometer to miles"+ \

"Enter m to converts miles to kilometer: ")

#if statement to execute the user choice of conversion

#Calls the kilometer_to_miles function

if user_input.lower() == 'k':

km = float(input("Enter kilometer to convert to mile: "))

print (km, "makes" ,format(kilometer_to_miles(km),'.2f') , "miles")

#calls the miles_to_kilometer function

elif user_input.lower() == 'm':

miles = float(input("Enter miles to convert to kilometer: "))

print (miles, "miles makes" ,format(miles_to_kilometer(miles),'.2f'),"kilometer")

#execute if the user's inpupt is none of the above

else:

print("invalid input.")

restart = input ("Enter Y to enter another value and N to quit.")

Output:
