elif python

1The elif statement allows you to check multiple expressions for TRUE 
2and execute a block of code as soon as one of the conditions evaluates
3to TRUE. Similar to the else, the elif statement is optional. However,
4unlike else, for which there can be at most one statement, there can 
5be an arbitrary number of elif statements following an if.
