Question

Hello everyone it Sam again.I finally understand how to use the conditional statement so i decided to write a program that allow users of age 21 and above access a web page but some where long the line it broke and let any age access the web page.need help debugging it pls

Age = raw_input("Enter Age : ")
if Age < 21:
print ("You can't access this web page")
elif Age == 21:
print ("Go ahead welcome to this web page")
elif Age > 21:
print ("Welcome to our web page")

Answer 1

Whenever you have any `elif` statements in Python 2.7.x, you must finish with an `else` clause to be syntactically correct.

Answer 2

after adding to my block of codes else ie

Age = raw_input("Enter Age : ")
if Age < 21:
print ("You can't access this web page")
elif Age == 21:
print ("Go ahead welcome to this web page")
elif Age > 21:
print ("Welcome to our web page")
else:
print ("no permit for you")

i ran the program and it produced this

Enter Age : 12
Welcome to our web page
>>>
why

Answer 3

what do i do about this program running and producing the wrong output

Answer 4

`raw_input` interprets numbers as strings. You will want to make sure to convert your input to either a float or int if you want to do comparisons with it.

On a side note, remember that
```
if x > 0:
#do something
elif x <= 0:
#do something else
```
is the same as
```
if x > 0:
#do something
else:
#do something else
```

Answer 5

do numerical operations with it*

Answer 6

The print statements in your program look like Python3. In Python3 raw_input() is deprecated, ( not recommended, will probably be removed in the future ). input() is the preferred way to get user input.

In Python2, raw_input() returns a string that the user input. Like TuringTest said, you need to convert it to a numerical type before doing numerical comparisons. This line may be a little dense for you, but in this case this is how I would code it:

Age = int( raw_input("Enter Age : ") )

A couple of other things: Python2 doesn't use parenthesis in print statements, that's why I think you're using Python3. By convention ( Python will accept it, but programmers have decided.... ) variable and function names start with a lowercase letter. Names of classes start with uppercase. I'll put constants ( variables that don't change ) in all caps.

Answer 7

@Turing Test and @rsmith6559 you guy are the best my program runs correctly now like you said, raw_input returns to string.I followed your instruction and it worked.And @rsmith6559 i use python 2.7.9.I only used used parenthesis Because i thought that was where my problem was.I guess i was losing it.Thanks again.
