There are used to compare the memory locations of two operators. Example: #!/usr/bin/python a = 20 b = 20 if ( a is b ): print “Line 1 – a and b have same identity” else: print “Line 1 – a and b do not have same identity” if ( id(a) == id(b) ): print … Read more
Example: #!/usr/bin/python a = 10 b = 20 list = [1, 2, 3, 4, 5 ]; if ( a in list ): print “Line 1 – a is available in the given list” else: print “Line 1 – a is not available in the given list” if ( b not in list ): print “Line … Read more
Example: #!/usr/bin/python x = True y = False print(‘x and y is’,x and y) print(‘x or y is’,x or y) print(‘not x is’,not x) Output: x and y is False x or y is True not x is False Few more example: 1. if (five == 5) AND (two == 2): print five, two 2. … Read more
What is python? Python is an interpreted programming language. As it is a programming language so it tells a computer what to do. However, the computer doesn’t read the language directly – there are hundreds of programming languages, and it couldn’t understand them all. So, when someone writes a program, they will write it in … Read more
