Python Variable Subtracting and If/Else statements

[itchkowb]

I'm new to python, so I wanted to do a easy project to get some practice. I decided on a calculator that determines if you're of the age to drink alcohol. I'm in the US, so it's 21. I have the user input part working, but when it comes to the calculating part, I'm having some trouble. If anyone knows how to help or has some good resources, I'd be very appreciative. Here's my code:

current_year = 2019
alchohol_consumtion_age = 21
print("--------------------------------------")
print("~~~~~~DRINKING AGE CALCULATOR~~~~~~~")
print("--------------------------------------")
patron_year = input("What Year Were You Born In, My Friend? ")
print("Ok, so you were born in " + patron_year) 
patron_day = input('And what day might you have joined us on earth? ')
print("Ahhhh, the " + patron_day)
print("I had a cousin, who was born on the very same day! What a small world it is")
print("what a small world, indeed")
if current_year - int(patron_year) = < alchohol_consumtion_age:
print("Tsk, Tsk, no alcohol for you")
else: 
print("It's Beer O'Clock, my dude or dudette") 
print("Drink Responsibly")
print("-------------------------------------")

Also, whenever I run it, I get this error: 

Quote

 File "/home/brett/python test.py", line 12
    if current_year - int(patron_year) = < alchohol_consumtion_age:
                                       ^
SyntaxError: invalid syntax
Terminated

 

Thanks

 

(also if i left out any info im sorry, i didn't know what to and what not to post)

instead of = < do <= for less than or equal to

 

Also, make sure to indent the lines in the if and else statement since python uses indentation to structure logic:

if current_year - int(patron_year) <= alchohol_consumtion_age:
	print("Tsk, Tsk, no alcohol for you")
else: 
	print("It's Beer O'Clock, my dude or dudette")
