Please can someone tell me what this means for me python question; what does this sign mean (-=) ,(<=),(+=),(>=)

Answer 1

-= means decrease by
example:

a = 5
a -= 2
print(a)

will output 3

+= means increase by

example:

a = 5
a += 2
print(a)

will output 7

<= means less or equal

print(5 <= 5) # this will be true because 5 is equal to 5
print(3 <= 5) # this will be true because 3 is less than 5
print(7 <= 5) # this will be false because 7 is greater than 5

>= means bigger or equal

print(5 >= 5) # this will be true because 5 is equal to 5
print(3 >= 5) # this will be false because 3 is less than 5
print(7 >= 5) # this will be true because 7 is greater than 5

I hope this helps :)
