Python Methods with Description.

Python includes following list methods 

1) list.append(obj) = Appends object obj to list
 2) list.count(obj) = Returns count of how many times obj occurs in list
 3) list.extend(seq) = Appends the contents of seq to list
4) list.index(obj) = Returns the lowest index in list that obj appears
5) list.insert(index, obj) = Inserts object obj into list at offset index
6) list.pop(obj=list[-1]) = Removes and returns last object or obj from list
7) list.remove(obj) = Removes object obj from list
8) list.reverse() = Reverses objects of list in place
9) list.sort([func]) = Sorts objects of list, use compare func if given

Function with Description

1) cmp(tuple1, tuple2) = Compares elements of both tuples.
2) len(tuple) = Gives the total length of the tuple.
3) max(tuple) = Returns item from the tuple with max value.
4) min(tuple) = Returns item from the tuple with min value.
5) tuple(seq) = Converts a list into tuple.

Built-in Dictionary Functions & Methods

Python includes the following dictionary functions −

1) cmp(dict1, dict2) = Compares elements of both dict.

2) len(dict) = Gives the total length of the dictionary. This would be equal to the number of items in the dictionary.

3) str(dict) = Produces a printable string representation of a dictionary

4) type(variable) = Returns the type of the passed variable. If a passed variable is a dictionary, then it would return a dictionary type.

Python includes the following dictionary methods −

1) dict.clear() = Removes all elements of dictionary dict

2) dict.copy() = Returns a shallow copy of dictionary dict

3) dict.fromkeys() = Create a new dictionary with keys from seq and values set to value.

4) dict.get(key, default=None) = For key key, returns value or default if key not in dictionary

5) dict.has_key(key) = Returns true if key in dictionary dict, false otherwise

6) dict.items() = Returns a list of dict's (key, value) tuple pairs

7) dict.keys() = Returns list of dictionary dict's keys

8) dict.setdefault(key, default=None) = Similar to get(), but will set dict[key]=default if key is not already in dict.

9) dict.update(dict2) = Adds dictionary dict2's key-values pairs to dict.

10) dict.values() = Returns list of dictionary dict's values.
