What is namespace in Python? Namespaces in Python. A namespace is a collection of currently defined symbolic names along with information about the object that each name references. You can think of a namespace as a dictionary in which the keys are the object names and the values are the objects themselves.

What is if name == Main in Python?
Python files can act as either reusable modules, or as standalone programs. if __name__ == “main”: is used to execute some code only if the file was run directly, and not imported.
What is Lambda in Python?
Python Lambda Functions are anonymous function means that the function is without a name. As we already know that the def keyword is used to define a normal function in Python. Similarly, the lambda keyword is used to define an anonymous function in Python.
What is A += in Python?
The Python += operator lets you add two values together and assign the resultant value to a variable. This operator is often referred to as the addition assignment operator.
Python, by design, does not allow the use of the ++ “operator”. The ++ term, is called the increment operator in C++ / Java, does not have a place in Python.
Can I use HTML with Python?
If you’re interested in web development with Python, then knowing HTML and CSS will help you understand web frameworks like Django and Flask better. But even if you’re just getting started with Python, HTML and CSS can enable you to create small websites to impress your friends.
Tuple. Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and unchangeable.
What is loop in Python?
Looping means repeating something over and over until a particular condition is satisfied. A for loop in Python is a control flow statement that is used to repeatedly execute a group of statements as long as the condition is satisfied. Such a type of statement is also known as an iterative statement.
What are data types in Python?
Built-in Data Types
Text Type:
str
Numeric Types:
int , float , complex
Sequence Types:
list , tuple , range
Mapping Type:
dict
Set Types:
set , frozenset
What is float in Python?
Python float() Function
The float() function converts the specified value into a floating point number.
What is array in Python?
What are Python Arrays? Arrays are a fundamental data structure, and an important part of most programming languages. In Python, they are containers which are able to store more than one item at the same time. Specifically, they are an ordered collection of elements with every value being of the same data type.
¶ When he began implementing Python, Guido van Rossum was also reading the published scripts from “Monty Python’s Flying Circus”, a BBC comedy series from the 1970s. Van Rossum thought he needed a name that was short, unique, and slightly mysterious, so he decided to call the language Python.
What is difference between tuple and list in Python?
In Python, tuples are allocated large blocks of memory with lower overhead, since they are immutable; whereas for lists, small memory blocks are allocated. Between the two, tuples have smaller memory. This helps in making tuples faster than lists when there are a large number of elements.
What is a double in Python?
The Double Division operator in Python returns the floor value for both integer and floating-point arguments after division.
What does %s mean in Python?
The % symbol is used in Python with a large variety of data types and configurations. %s specifically is used to perform concatenation of strings together. It allows us to format a value inside a string.
How many data types are in Python?
In a programming language like Python, there are mainly 4 data types: String – It is a collection of Unicode characters (letters, numbers and symbols) that we see on a keyboard. Numerical – These data types store numerical values like integers, floating-point numbers and complex numbers.
Is Python float or double?
Python does not have a built-in double data type but it has float type that designates a floating-point number. You can count double in Python as float values are specified with a decimal point. All platforms represent Python float values as 64-bit “double-precision” values, according to the IEEE 754 standard.
Python’s floating-point numbers are usually 64-bit floating-point numbers, nearly equivalent to np.
Is Python case sensitive or not?
Is Python a Case-Sensitive Language? YES, Python is a case-sensitive programming language. This means that it treats uppercase and lowercase letters differently. Hence, we cannot use two terms having same characters but different cases interchangeably in Python.
What is int32 in Python?
int32. A 32-bit signed integer whose values exist on the interval [−2,147,483,647, +2,147,483,647] .
What are 3 types of list in Python?
Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage.
How do I run a 64 bit integer in Python?
Similarly, if you want to use 16 bits, 32 bits, and 64 bits to store integers, the ranges would be: 16-bits ~ [-215, 215 – 1] = [ -32,768 , 32,767 ] 32-bits ~ [-231, 231 – 1] = [- 2,147,483,648 , 2,147,483,647 ] 64-bits ~ [-263, 263 – 1] = [ -9,223,372,036,854,775,808 , 9,223,372,036,854,775,807 ]
