In C, ++ and -- operators are called increment and decrement operators. They are unary operators needing only one operand. Hence ++ as well as -- operator can appear before or after the operand with same effect. That means both i++ and ++i will be equivalent. , and , both will make i=6. However, when increment expression is used along with assignment operator, then operator prec.....
List is a sequence of elements. Any element in the sequence is accessible by its position in sequence. The index starts with 0. Hence list[2] will return element at index 2, the third in the list i.e. 50.
Hello Everyone, I am new to Python. May I know why I am getting the error in the following piece of code (where I am trying to print a value 1 more than the value of num:- , , , Here in the TypeError, what is the 'int' object and what is the 'str' object that are being referred to ?? How can this error be corrected ?? Thanks & Regards, H.C.
This can be corrected by putting n+1 in brackets i.e. (n+1) , Using %d casts the object following % to string. Since a string object can't be concatnated with a number (1 in this case) interpreter displays typeerror.
Highest Common Factor or Greatest Common Divisor of two or more integers is the largest positive integer that evenly divides the numbers without a remainder. For example, the GCD of 8 and 12 is 4. ,
An OrderedDict is a dictionary subclass that remembers the order in which its contents are added, It is defined in collections module of Python library. OrderDict remembers the order of addition of key-value pairs in a dictionary ,
An OrderedDict is a dictionary subclass that remembers the order in which its contents are added, supporting the usual dict methods.If a new entry overwrites an existing entry, the original insertion position is left unchanged. Deleting an entry and reinserting it will move it to the end. ,
Python's set object represents built-in set class. Different set operations such as union, intersection, difference and symmetric difference can be performed either by calling corresponding methods or by using operators. Union by method , , Intersection by method , Intersection & operator , Difference method , Difference - operator ,
Every class in Python, whether built-in or user defined is inherited from object class. The object class has a number of properties whose name is preceded and followed by double underscores (__). Each of these properties is a wrapper around a method of same name. Such methods are called special or magic methods. The magic methods __lt__(), __gt__(), __eq__(), __ne__(), etc. are overridden i.....
Although infinity doesn't have a concrete representation, the closest number to negative infinity is represented as return value of float() function with '-inf' as argument ,
