Today I am going to explain my understanding on some of the amazing functions available in python's itertools module. These too are very essential functions, and a clear understanding of these methods would help one in becoming a better python programmer. All these methods will return an iterable object as response.
A count method is similar to range and xrange methods,except the fact that it does'nt need a stop variable. The implementation is shown below,
A cycle method loops over the given list of items again and again.
Make an iterator that drops elements from the iterable as long as the predicate is true; afterwards, returns every element.Here, 1,4 fails the test and once 6 passes,all other elements are returned.
this method filters the data such that the data that pass validation are returned as result.
