While doesn't break with a an input string












0















How can I break the while with a string input? I was trying this, but the first if is ignored:



from itertools import cycle;
ewe=cycle([0]);
Nom_join="";
Principal_loop=True;
Cont_Error1=0;
while(Principal_loop==True):

for i in ewe:
Nom_join=input("give me a name to search: -> ");
if (Nom_join==""):
print("you cant do that");
Cont_Error1+=1;
elif(Nom_join==" "):
print("you cant do that");
Cont_Error1+=1;
elif(Nom_join.isdigit()):
print("you cant do that")
Cont_Error1+=1;
elif(Nom_join=="*"):
Principal_loop=False;
else:
break;

    Please remove the semicolons, they hurt every Python developer's eyes.

Try adding a break statement after Principal_loop=False. And yes, please remove semicolons and add spaces before and after operators to conform with PEP 8 guidelines. Also, no parentheses after conditional statements.



from itertools import cycle
ewe = cycle([0])
Nom_join = ""
Principal_loop = True
Cont_Error1 = 0

while Principal_loop == True:
for i in ewe:
Nom_join = input("give me a name to search: -> ")
if Nom_join == "":
print("you cant do that")
Cont_Error1 += 1;
elif Nom_join == " ":
print("you cant do that")
Cont_Error1 += 1
elif Nom_join.isdigit():
print("you cant do that")
Cont_Error1 += 1
elif Nom_join == "*":
Principal_loop = False
break
else:
break


I'm really not sure why you need to initiate a cycle of infinite zeros... There's also a lot of other simplifications that can be made. It seems far simpler to do this:



Cont_Error1 = 0
while True:
Nom_join = input("give me a name to search: -> ")
if Nom_join in {"", " ", "*"} or Nom_join.isdigit():
print("you can't do that")
Cont_Error1 += 1;
else:
break
