Python 3 - IF Statement
The IF statement is similar to that of other languages. The if statement contains a logical expression using which the data is compared and a decision is made based on the result of the comparison.
Syntax
if expression: statement(s)
If the boolean expression evaluates to TRUE, then the block of statement(s) inside the if statement is executed. In Python, statements in a block are uniformly indented after the : symbol. If boolean expression evaluates to FALSE, then the first set of code after the end of block is executed.
Flow Diagram

Example
#!/usr/bin/python3 var1 = 100 if var1: print ("1 - Got a true expression value") print (var1) var2 = 0 if var2: print ("2 - Got a true expression value") print (var2) print ("Good bye!")
Output
When the above code is executed, it produces the following result −
1 - Got a true expression value 100 Good bye!
