By definition, tuple object is immutable. Hence it is not possible to remove element from it. However, a workaround would be convert tuple to a list, remove desired element from list and convert it back to a tuple.>>> T1=(1,2,3,4) >>> L1=list(T1) >>> L1.pop(0) 1 >>> L1 [2, 3, 4] >>> T1=tuple(L1) >>> T1 (2, 3, 4)

A dictionary object is mutable. Hence one dictionary object can be used as a value component of a key. So we can create a nested dictionary object another dictionary object is defined as value associated with key.>>>> students={"student1":{"name":"Raaj", "age":23, "subjects":["Phy", "Che", "maths"], "GPA":8.5}, "student2":{"name":"Kiran", "age":21, "subjects":["Phy", "Che", "bio"], "GPA":8.25}}Read More

There are different ways to iterate through a tuple object. The for statement in Python has a variant which traverses a tuple till it is exhausted. It is equivalent to foreach statement in Java. Its syntax is −for var in tuple: stmt1 stmt2ExampleFollowing script will print all items in the ... Read More

In Python 2.x, both methods are available, but in Python 3.x iteritems() is deprecated. As far as Python 2.x is concerned, items() method of dictionary object returns list of two element tuples, each tuple containing key and value. On the other hand iteritems() is a generator which provides an iterator ... Read More

To convert to tuple of string objects into a single string, you can use join() function. Ensure that trget string is initialised to null string >>> T1='1','2','3' >>> s=''.join(T1) >>> s '123'

In Python, assignment operator doesn’t create a new object, rather it gives another name to already existing object. This can be verified by id() function >>> L1 = [1, 2, 3, 4] >>> L2 = L1 >>> id(L1) 185117137928 >>> id(L2) 185117137928 To actually copy a list, following ... Read More

A simple and straightforward solution is to append items from sublists in a flat list using two nested for loops. lst = [[10, 20, 30, 40], [50, 60, 70, 80], [90, 100, 110, 120]] flatlist = [] for sublist in lst: for item in sublist: ... Read More

Each Python object is assigned a unique identification number when it is stored in memory. It can be fetched by id() function. The is operator compares id() of two objects and returns True if both objects have same value otherwise it returns false. The is not operator on the other ... Read More

Following table shows all assignment operators − Operator Description Example = Assigns values from right side operands to left side operand c = a + b value of a + b into c += It adds right operand to the left operand and ... Read More

Bitwise operators operate upon bits as operands. Following bitwise operators are defined in Python − & (bitwise AND): returns 1 if both bit operands are 1 | (bitwise OR): returns 1 even if one of two bit operands is 1 ^ (bitwise XOR): returns 1 only if one operand ... Read More
