If I enter any value less than 24, it does print the "You will be old..." statement. If I enter any value greater than 24 (ONLY up to 99), it prints the "you are old" statement.
The problem is if you enter a value of 100 or greater, it prints the "You will be old before you know it." statement.
print ('What is your name?')
myName = input ()
print ('Hello, ' + myName)
print ('How old are you?, ' + myName)
myAge = input ()
if myAge > ('24'):
print('You are old, ' + myName)
else:
print('You will be old before you know it.')
Well, to write greater than or equal to in Python, you need to use the >= comparison operator. It will return a Boolean value – either True or False. The "greater than or equal to" operator is known as a comparison operator. These operators compare numbers or strings and return a value of either True or False .
== and is are two ways to compare objects in Python. == compares 2 objects for equality, and is compares 2 objects for identity.
The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory. In the vast majority of cases, this means you should use the equality operators == and !=
In the case of floating-point numbers, the relational operator (==) does not produce correct output, this is due to the internal precision errors in rounding up floating-point numbers. In the above example, we can see the inaccuracy in comparing two floating-point numbers using “==” operator.
You're testing a string value myAge
against another string value '24'
, as opposed to integer values.
if myAge > ('24'):
print('You are old, ' + myName)
Should be
if int(myAge) > 24:
print('You are old, {}'.format(myName))
In Python, you can greater-than / less-than against strings, but it doesn't work how you might think. So if you want to test the value of the integer representation of the string, use int(the_string)
>>> "2" > "1"
True
>>> "02" > "1"
False
>>> int("02") > int("1")
True
You may have also noticed that I changed print('You are old, ' + myName)
to print('You are old, {}'.format(myName))
-- You should become accustomed to this style of string formatting, as opposed to doing string concatenation with +
-- You can read more about it in the docs. But it really doesn't have anything to do with your core problem.
