I'm new to programming, fyi. I want my program to restart back to the top based on what the user inputs. It will proceed if the user inputs 2 names. If they input 1 name or more than 2 names, it should restart the program but I'm not sure of how to do this.
def main():
print("Hello, please type a name.")
first_name, last_name = str(input("")).split()
while input != first_name + last_name:
print("Please enter your first name and last name.")
main()
You should use a while loop and check the length of the split before assigning:
def main():
while True:
inp = input("Please enter your first name and last name.")
spl = inp.split()
if len(spl) == 2: # if len is 2, we have two names
first_name, last_name = spl
return first_name, last_name # return or break and then do whatever with the first and last name
Use try/except
Well, your program didn't work for me to begin with, so to parse the first and last names simply, I suggest:
f, l = [str(x) for x in raw_input("enter first and last name: ").split()]
Also your while loop will just, like, break your life if you run it without good 'ol ctrl+c on hand. So, I suggest:
def main():
print “type your first & last name”
try:
f, l = [str(x) for x in raw_input("enter first and last name: ").split()]
if f and l:
return f + ‘ ‘+ l
except:
main()
The except: main() will re-run the program for you on error.
