What is wrong with this code?

import time
import sys

This program takes some input (they will be the years) and then
adds it to 4 ages. For example, if you give the ages 10, 11, 12
and 13 it will return the age added to your first input.
"""
# These are the years to add.
print "Enter the number of years to be added:"
yearstoadd = int(sys.stdin.readline())

print "Enter the first age:"
num1 = int(sys.stdin.readline())

    print "Sorry, this is a very big age"
break
else:    
    print "Enter the second age:"
    num2 = int(sys.stdin.readline())
    if num1 > 100:
        print "Sorry, this is a very big age"

When I run this code, this error appears:C:\Documents and Settings\Administrator\Desktop>agefinder.py

SyntaxError: invalid syntax

You don't seem to understand how if statements, nor general syntax in Python works.

In Python, we mark blocks of code by

some_statement:
    some code
code not in block

That's it. Just indent - there's no need to follow your statements up with "break". Remove your breaks.

But I want my program to stop if the ages are above 100. In that case how do I do it?

Have a look at the code here - http://docs.python.org/tutorial/controlflow.html#if-statements

And read it. Then, have a look at your code, and try to see what you're doing wrong. It'll be quite obvious if you're diligent in your reading.

I get it.The program will break even if I don't put "break." Then what's the use of break? Sorry if I am irritating you.

[griswolf]

The Python break key word is a way to break out of a loop. Just that. So, for instance

result=None
for i in range(1000000000): # really long loop
    result = check_item(i)
    if are_we_done_looking(i, result):
        break # so we don't have to finish the loop
if result:
    generate_report(result)
else:
    print("Useful result not found.")

Please go read an introduction to Python programming. For instance these, though there are probably hundreds. http://docs.python.org/tutorial/

break command is used to exit the current for or while statement from middle of loop.

No, you're not annoying me, you've just not understood. I suggest you read some more tutorials and see if they help you :)

Okay.Need a little more help.

Is there something wrong with this?

import time
import sys
print """Enter your name
"""
myname = chr(sys.stdin.readline())
print """Hello %s. How are you today?
Would you mind entering your age?:
"""% myname
myanswer = (sys.stdin.readline())
if myanswer == "yes":
    myage = int(sys.stdin.readline())
    print "Hello %s. You are %s years old."%(myname, myage)
    time.sleep(5)
    sys.exit()
else:
    print "Suit yourself. Bye %s!"%  myname
    sys.exit(5)

    sys.exit(5)

Is there something wrong ? is not a good question. Good questions areDoes it fail with exception ? (then study the error message)
Does it produce the expected result ? (if not, work more)
Could the code be improved ? (usually yes, but it depends on your knowledge of python)
Here I suggest something like

import time
import sys
myname = raw_input("""Enter your name: """).strip()

print """Hello %s. How are you today?""" % myname

myanswer = raw_input("Would you mind entering your age? [yes] ").strip().lower()
if myanswer in ('', 'y', 'yes'):
    myage = raw_input()
    while True:
        try:
            myage = int(myage.strip())
            break
        except ValueError:
            myage = raw_input("Please enter a numeric age: ")
    print "Hello %s. You are %s years old." % (myname, myage)
    time.sleep(5)
    sys.exit()
else:
    print "Suit yourself. Bye %s!"%  myname
    sys.exit(5)
