    The pass statement is used as a placeholder for future code. It is a null operation.
    When the pass statement is executed , nothing happens but you avoid getting an error
    when empty code is not allowed. Empty code is not allowed in loops, function definitions,
    class definitions or in if statements.

    Code Example :

    for a in ‘DataMonk’:
    if a == ‘M’:
    pass
    print ‘This is pass block’
    print ‘current letter : ‘ , letter
    print ‘Finish’

    output:
    Current Letter : D
    Current Letter : A
    Current Letter : T
    Current Letter : A
    This is pass block
    Current Letter : O
    Current Letter : N
    Current Letter : K
    Finish

    It is used as a null operator. If statements cannot be empty, but if you for some reason have an if statement with no content , put in the “pass” statement to avoid error in the code.
    Code;
    a = 33
    b = 200

    if b>a:
    pass

    Pass is used when a statement is required syntactically but you do not want any command or code to execute. It is a null operation; nothing happens when it executes. We generally use it as a placeholder.

    Examples:
    sequence = {‘p’, ‘a’, ‘s’, ‘s’}
    for val in sequence:
    pass

    class Example:
    pass
