In my attempt to learn Python I'm writing a small (useless) program to
help me understand the various concepts. I'm going to add to this as I
learn to serve as a single place to see how something works,
hopefully. Here is the first approach:
name = input('Please enter your name: ')
print('Hello', name)
while True:
try:
age = int(input('Please enter your age: '))
break
except ValueError:
print('That was not a valid number. Please try again.')
permitted = list(range(18, 31))
if age in permitted:
print('Come on in!')
elif age < min(permitted):
print('Sorry, too young.')
elif age > max(permitted):
print('Sorry, too old.')
input('Press any key to exit.')
That works fine. Then I've tried to use functions instead. The first
two work fine, the third fails:
def getName():
name = input('Please enter your name: ')
print('Hello', name)
def getAge():
while True:
try:
age = int(input('Please enter your age: '))
break
except ValueError:
print('That was not a valid number. Please try again.')
def checkAge():
permitted = list(range(18, 31))
if age in permitted:
print('Come on in!')
elif age < min(permitted):
print('Sorry, too young.')
elif age > max(permitted):
print('Sorry, too old.')
getName()
getAge()
checkAge()
I get this error message: NameError: global name 'age' is not
defined.
I'm stuck, can someone help? Thanks.
