Python Logical Operators: and, or, not We can apply for all types. For boolean Types Behaviour:and –> If both arguments are True then only result is Trueor –> If at least one arugemnt is True then result is Truenot –> ComplementTrue and False –> FalseTrue or False –> Truenot False –> True For non-boolean Types…

None Data Type None means nothing or No value associated. If the value is not available, then to handle such types of cases None is introduced. It is something like a null value in Java. Eg:def m1():a=10print(m1())None
Datatype Description Is Immutable? Example Int We can use to represent the whole/integral numbers Immutable >>> a=10 >>> type(a) <class ‘int’> Float We can use to represent the decimal/floating point numbers Immutable >> b=10.5 >>> type(b) <class ‘float’> Complex We can use to represent the complex numbers Immutable >> c=10+5j >> type(c) <class ‘complex’> >>>…

Python dict Data Type If we want to represent a group of values as key-value pairs then we should go for dict data type. Eg: d = {101:’durga’,102:’ravi’,103:’shiva’} Duplicate keys are not allowed but values can be duplicated. If we are trying to insert an entry with the duplicate key then old value will be…

It is exactly the same as set except that it is immutable. Hence we cannot use add or remove functions.
Python set Data Type: If we want to represent a group of values without duplicates where the order is not important then we should go for set Data Type.1) Insertion order is not preserved2) Duplicates are not allowed3) Heterogeneous objects are allowed4) Index concept is not applicable5) It is a mutable collection6) Growable in nature…

bytearray is exactly same as bytes data type except that its elements can be modified. Eg 2:
bytes Data Type bytes data type represents a group of byte numbers just like an array. Conclusion 1: The only allowed values for byte data type are 0 to 256. By mistake, if we are trying to provide any other values then we will get a value error. Conclusion 2: Once we create a bytes…
