Checking for Inequality in Python

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

Let there be a variable:

pythontst = 5

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

pythonif 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:

pythontst = 0

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

Задание 1

Given a variable:

pythontst = -4

Check that it is not equal to 4.

Задание 2

The following code is given:

pythontst = 123

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

Tell me what will be output to the console.

Задание 3

The following code is given:

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

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

Tell me what will be output to the console.

Задание 4

The following code is given:

pythontst1 = [3, 4, 5, 6]
tst2 = list('3456')

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

Tell me what will be output to the console.
