The below code is for python3.

temperature=20
thermo=15
def increase_temp():
if temperature>=15:
thermo+=5
print(thermo)
return thermo
print(increase_temp())

if I pass the argument in function it works.

local variable is referenced before assignment, maybe something like this is a solution?

temperature=20
thermo=15
def increase_temp():
if temperature >= 15:
global thermo
thermo = temperature + 5
return thermo
print(thermo)
print(increase_temp())

It will work but, 'thermo' seems to be a global variable as it was defined before function.

temperature=15
thermo=15
def increase_temp():
if temperature >= 15:
thermo = temperature + 5
return thermo
print(thermo)
else:
message = "Everything is OK"
return message
print(increase_temp())

ok, I didn't drink coffee...now, I think this is it :)

Yeah, that works too. Is it that the global variable (Thermo), if once updated inside the function, becomes a local variable?

global variables can be used inside or outside of functions and stays global

Once you change the value of a global variable inside a function, it's no longer a global variable but a local variable.
