Hi,
I have to write a script that asks the user for names one at a time, and
accept the name only if the user did not gave it before. The script has to
do this until it gets 3 unique names.
So far I have this:
def GetNames():
names=[]
while len(names)<3:
name=raw_input("Name: ")
if name in names:
print name, "is already in the data. Try again."
if name not in names:
names.append(name)
names.sort()
for each in names:
print "Hurray for", each +"!"
print
However I cannot use the len() built in function. The Teacher is asking for
another solution that does not use the len() t
I know I can do it using the command:
def Ask
def GetNames(how_many):
names=[]
for el in range(how_many):
name=raw_input("Name: ")
if name in names:
print name, "is already in the data. Try again."
if name not in names:
names.append(name)
names.sort()
for each in names:
print "Hurray for", each +"!",
print
I cannot get 3 names, and it is easy to understand why (because the loop
only iterates 3 times). But I don't know how to ask the user for names one
at a time and to obtain 3 names and an output that looks like this:
Name #1: Lewis
Name #2: John
Name #3: John
John is already in the data. Try again.
Name #3:
Name #3: Chris
Hurray for Chris! Hurray for John! Hurray for Lewis!
Many Thanks!
