Complex if-elif in python

I am trying to create a complex if else statement in python. These statements should check two variables. The sample code:

    if value1 == 0.1 and value2 > 2.05:
       value1  = value1 + 0.1
       return value1  
    elif value1  == 0.2 and value2 > 1.85:
       value1  = value1  + 0.1
    elif value1  == 0.3 and value2 > 1.95:
       value1  = value1  + 0.1
    elif value1  == 0.4 and value2 > 2.05:
       value1  = value1  + 0.1
    ...
    if value1 == 0.1 and value2 < 1.75:
       return value1  
    elif value1  == 0.2 and value2 < 1.85:
       value1  = value1  - 0.1
    elif value1  == 0.3 and value2 < 1.95:
       value1  = value1  - 0.1
    elif value1  == 0.4 and value2 < 2.05:
       value1  = value1  - 0.1
    ....

In total I have an if or elif for every value1 from 0.1 - 1. Every time value2 is a different value. What I want to do is to check also if value2 is less than a value in order to decrease value1 = value -1. Which is the most clever way to do so, without adding many if -elif statements?

If there is no pattern or it's so complex that it can't be easily constructed with a loop then I would do something like this:

eq_gt_pairs = ((0.1, 2.05), (0.2, 1.85), (0.3, 1.95), (0.4, 2.05)) # ...

eq_lt_pairs = ((0.1, 1.75), (0.2, 1.85), (0.3, 1.95), (0.4, 2.05)) # ...

for pair in eq_gt_pairs:
    if value1 == pair[0] and value2 > pair[1]:
        return value1 + 0.1

for pair in eq_lt_pairs:
    if value1 == pair[0] and value2 < pair[1]:
        return value1 - 0.1
