Grouping Conditions in Python

Although the operation and takes precedence over or, it is often more convenient to use grouping parentheses to make the precedence of the operations explicit:

tst = 3
	
if (tst > 0 and tst < 5) or (tst > 10 and tst < 20):
	print('+++')
else:
	print('---')

In the code below, specify the priority of the operations explicitly:

tst = 3
	
if tst > 5 and tst < 10 or tst == 20:
	print('+++')
else:
	print('---')

In the code below, specify the priority of the operations explicitly:

tst = 3
	
if tst > 5 and tst > 0 and tst < 3:
	print('+++')
else:
	print('---')

In the code below, specify the priority of the operations explicitly:

tst = 3
	
if tst == 9 and tst > 10 and tst < 20 or tst > 20 and tst < 30:
	print('+++')
else:
	print('---')
