Python For Dummies | Shahir Kazi

Dear Shariq,

I challenge you to read through this article if you think you are literate enough. You probably know by now how to print strings with the print() function and compare two variables against. Just to refresh your mind on it I'll write out an example of some code that uses the comparators. Lines starting with the # symbol are comments - meaning they aren't executed. This is useful for describing what a line does to other people reading your code or even yourself when you come back to read it again in the future.

# let's declare some variables 
a = 1
b = 1

# the '==' symbol checks if two variables are equal to one another. 
print(a==b) # prints True
c = (a==b) # stores the value of (a==b) into c
print(c) # prints True

# the < symbol checks if something is less than the other
# a good way to remember how this works is to imagine the open mouth pointing to the greater value
print(a < b) # prints False since a is not less than b

# and vice versa for the > symbol
print(a > b) # checks if a is greater than b 

# this last symbol is a little tricky: the '<=' symbol
# it checks if something is either less than OR equal to the other value
print(a <= b) # prints True. can you explain why?

Alright, that concludes our lesson on the comparator symbols. Try running them in PyCharm and report to me what you find.

For our next lesson, we'll look at for arithmetic symbols.
