How to use the IF statement for the Python Getting Started tutorial

The IF statement in Python is similar to other languages. The IF statement contains a logical expression that uses that data to compare and make decisions based on the results of the comparison.
Grammar:

The syntax for the IF statement in the Python programming language is:

If expression:  statement (s)

If the Boolean expression evaluates to True, then the IF statement block is executed. If the Boolean expression of the IF statement evaluates to False, then the first set of code is executed.

The Python programming language assumes that any nonzero and non-null is true, and if it is zero or null, the value is assumed to be false.

Example:

#!/usr/bin/pythonvar1 = 100if var1:  print "1-got a true expression value"  print var1var2 = 0if var2:  print " 2-got a true expression value "  print Var2print" Good bye! "

When the above code is executed, the following results are produced:

1-got a true expression Value100good bye!
