Which is better Python 2 or Python 3?
Why they use it:
- Python is not traditionally a typed language, but Python v3.5 supports typing, which removes development conflicts when working new pieces of code.
- Each newer version of Python continues to get faster runtime. Meanwhile, nobody’s currently working to make Python 2.7 work faster.
- Community support is better with Python 3.
What does not equal in Python?
This not equal to the operator is a special symbol in Python that can evaluate logical or arithmetic expressions. This is usually represented as “ != ” and “ is not ” for operating this not equal to operator. In Python, the values that this not equal to the operator operates on is known as an operand.
What is the difference between append and extend in Python?
append () and extend () in Python
- append () Syntax: list_name.append (‘value’) It takes only one argument. This function appends the incoming element to the end of the list as a single new element.
- Example
- Output
- extend () Extend adds each element to the list as an individual element. The new length of the list is incremented by the number of elements added.
- Example
- Output
Does not equal in Python?
The not equal is a comparison operator used to check if the first variable is not equal to the second variable. It has two return values. If the variables are not equal, it returns TRUE otherwise FALSE. Both value and data type of the variables are considered while returning TRUE or FALSE. Removed in Python 3, but was widely used in Python 2.
What is the difference between single slash and double slash in Python?
Python has two division operators, a single slash character for classic division and a double-slash for “floor” division (rounds down to nearest whole number). Classic division means that if the operands are both integers, it will perform floor division, while for floating point numbers, it represents true division.
What is difference between and and & in Python?
Here is a list of the differences between 'and' and '&' in Python. The and is a type of Logical AND that returns in a True form whenever both the operands are also true. The &, on the other hand, is a bitwise operator used in the Python language. It basically acts on various bits and performs operations bit by bit.
What's the difference between () and []?
() is a tuple: An immutable collection of values, usually (but not necessarily) of different types. [] is a list: A mutable collection of values, usually (but not necessarily) of the same type.
What does &= mean in Python?
It means bitwise AND operation. Example : x = 5 x &= 3 #which is similar to x = x & 3 print(x)
What does [:- 1 in Python do?
What does [:-1] in Python actually do and why would you want to use it? [:-1] in Python is a slice operation used on strings or lists and captures all contents of the string or list except for the last character or element.
What is a [- 1 in Python?
Python also allows you to index from the end of the list using a negative number, where [-1] returns the last element. This is super-useful since it means you don't have to programmatically find out the length of the iterable in order to work with elements at the end of it.
What's difference between char's [] and char * s in C?
Difference between char s[] and char *s in C The s[] is an array, but *s is a pointer. For an example, if two declarations are like char s[20], and char *s respectively, then by using sizeof() we will get 20, and 4.
What is the difference between * and * in Matlab?
* is matrix multiplication while . * is elementwise multiplication. In order to use the first operator, the operands should obey matrix multiplication rules in terms of size. Show activity on this post.

Can I use ++ in Python?
Python does not allow using the “(++ and –)” operators. To increment or decrement a variable in python we can simply reassign it. So, the “++” and “–” symbols do not exist in Python.
Is ++ valid in Python?
In C, C++, Java etc ++ and -- operators increment and decrement value of a variable by 1. In Python these operators won't work. In Python variables are just labels to objects in memory.
What is Itemgetter in Python?
itemgetter (*items) Return a callable object that fetches item from its operand using the operand's __getitem__() method. If multiple items are specified, returns a tuple of lookup values. For example: After f = itemgetter(2) , the call f(r) returns r[2] .
Is it formal to use &?
An ampersand (&) is a typographical symbol that is rarely used in formal writing. It is read aloud as the word and and is used as a substitute for that word in informal writing and in the names of products or businesses.
What is the difference between '/' and operator in Python Class 7?
'/' is the division operator. '//' is the floor division operator.
What is the difference between and and/or operator?
The difference between AND, OR is that AND evaluates both conditions must be true for the overall condition to be true. The OR evaluates one condition must be true for the overall condition to be true. In the OR result, if name is John then condition will be true. If any row has the age 22, then it will be true.
What is the difference between and == operators in Python?
The '==' operator checks whether the two given operands are equal or not....Output:===It is an assignment operator.It is a relational or comparison operator.It is used for assigning the value to a variable.It is used for comparing two values. It returns 1 if both the values are equal otherwise returns 0.1 more row•Apr 5, 2019
What does it mean when a compiler checks if a statement is true?
If the first statement is False, it does not check the second statement and returns False immediately. This is known as “lazy evaluation”. If the first statement is True then the second condition is checked and according to rules of AND operation, ...
When is an integer value considered false?
Note: When an integer value is 0, it is considered as False otherwise True when using logically.
What is ‘&’ in Python?
The &, on the other hand, is a bitwise operator used in the Python language. It basically acts on various bits and performs operations bit by bit.
What does the "and" test?
The ‘and’ expression tests if both the expressions used are True (logically).
What is the difference between JavaScript and Python?
The most obvious difference that anyone will notice right away from looking at code in both Python and JavaScript is that the syntax is quite different. JavaScript has syntax like C and Java, while Python has a more stripped-down syntax with fewer special symbols.
What does / mean in Python?
In python, / means division or normal division.Here ,the output will be a float number.
What is an operator in Python?
Operators are the constructs which can manipulate the values of the Operands. Consider the expression 2 + 3 = 5, here 2 and 3 are Operands and + is called Operator. Python has different type of Operators.
What is the problem with tuples in Python?
The problem with tuples in Python is that they don’t have field names, and would be much more useful if they did. However, there is a namedtuple type in the collections module which solves this problem for us:

Is C++ faster than Python?
C++ is faster in speed as compared to python. Rapid Prototyping. Rapid Prototyping is possible due to the small size of the code. Rapid Prototyping not possible due to larger code size. Efficiency. Easier to maintain, object-oriented and simpler to use. Less clean and manageable in comparison to python. Nature.
