Checking for Inequality in Python

There is also an operator != which tests for inequality.

Let there be a variable:

tst = 5

Let's check that it is not equal to 0:

if tst != 0:
	print('+++') # this will work because the variable is NOT equal to 0
else:
	print('---')

Now let's change the value of the variable:

tst = 0

if tst != 0:
	print('+++')
else:
	print('---') # this will work because the variable is equal to 0

Given a variable:

tst = -4

Check that it is not equal to 4.

The following code is given:

tst = 123

if tst != 123:
	print('+++')
else:
	print('---')

Tell me what will be output to the console.

The following code is given:

tst = ['a', 'b', 'c']

if tst[1] != 'c':
	print('+++')
else:
	print('---')

Tell me what will be output to the console.

The following code is given:

tst1 = [3, 4, 5, 6]
tst2 = list('3456')

if tst1 != tst2:
	print('+++')
else:
	print('---')

Tell me what will be output to the console.
