List Functions

This Python tutorial gives a list of various list functions that can be applied to a list .

List Methods:

List Data Type has different types of methods and some are there:

• Each and every list method is usually represented in the form object.modulename()
• If any iterable has to be converted int list then list() should be useed 

list.append()

• list.append(x)
• Appends x to the end of list. x can be a variable or  constant interger or any other character as we can have any type of content in the list.
• list.append(x) is similar to a[len(a):]=[x]  

list.extend()

• list.extend(iterable)
• Appends the iterable to the end of the list. Where iterable is a list or a range() of values or a string or a tuple .
• list.extend(iterable) is equivalent to a[len(a):]=iterable 

list.insert()

• list.insert(i,x)
• In this method i is the index and x is the value to be inserted ,Hence this function inserts x in the list with an index i.
• a[i]=x is equivalent to list.insert(i,x)

list.remove()

• list.remove(x)
• Removes the first element which matches with x.

list.pop([i])

• a.pop()
• Removes the last element in the list

list.index()

• list.index(x,i)
• Returns the index which is the second instance of the variable x.

list.count()

• list.count(x)
• Counts all the instances of x.

list.sort()

• list.sort()
• arranges the content of the list in ascending order.

list.reverse()

• list.reverse()
• simply reverses the content of the list ie the last element comes to the first and the first to the last.

list.copy()

• list.copy()
• returns a copy of the list.
• Similar to a[:]      

     Take a list apply all these functions seems to be intresting
