What is interpreter
An interpreter is a program that directly executes the instructions in a high-level language, without converting it into machine code.
How to convert python code to C code
We have to use Cython a language
Which programming language is used by developers of python
Rpython,
Its used by programmers that develop python itself , since it doesn’t need an interpreter
How to get this output without fsrtring ,

What is the special character in Python
Backlash is an special character in python
What are literals
Constant values or fixed value ,
Values that never change during the whole execution of program
What is the output of this code,
give reasons in support of ur answer ?
mynum = 0o123
type(mynum)
printy(mynum)
int
83
python assumes octal numbers as integers ,
so the code assigns the decimal value 83 to the variable myoctal, and then it prints the value of myoctal using the print function.
How to save octal number in variable
myOctalNumber = 0o123
How to save hexadecimal number in variable
myhexaNumber = 0x123
How to print object class of identifiers ?
We have to use type method()
a = 10
type(a)
How to write below decimal number in short or scientific notation - 0.000005
5e-6 in decimal form = 0.000005
How to write Boolean values in Python
True , False
Hello to “Python”
How to create this type of string constant
We have to use special character of python ,
the backslash character , or we use single quotes
Conversion
mystr = “Hello to "Python"”
mystr = ‘Hello to “Python”’ ‘
Create an constant of octal number number , and print it to decimal
myoctal= 0o123 # it converted to base 10 first & then assighned to variable
print(“Decimal Equivalent is “,myoctal)
What are the unary operators in Python
Operators which works on single operands.

22
What is the output of print(not b)
name ‘b’ is not defined
What is the Presidence of operators in Python
In python we have eight levels of Presidence
- Parenthesis ()

What are the division operators in Python
/ Division
% Modulus
// Floor Division
What are the bitwise operators in Python
«_space;Bitwise Left »_space; Right Shift
& Bitwise AND
^ Bitwise XOR
| Bitwise OR
What is the presidence of bitwise operators
- Bitwise Shift
- Bitwise AND
- Bitwise XOR
- Bitwise OR
What is the presidence of Logical Operators
- not
- and
- or
What is the output of print(1 and 200) , give reason in support of ur answer
in a logical AND operation like “1 and 200,” the result would be the second operand, which is 200. So, in this context, the output is indeed 200

How to remove \n default behaviour of print function
We have to use keyword argument, to remove \n default behaviour of print function
~~~
print(“Hello to”,end=” “)
print(“Python “)
~~~
How to print symbol between two strings in single print statement
We have to use keyword argument,
~~~
print(“Hello to”,”Python”,sep=”#”)

What is the output of -6 / 4 ?
-1.5
What is the output of 6. // 4
1.0
Floor Division rounds down to the nearest integer,The actual result of 6 / 4 is 1.5 , but floor division rounds down to 1 .
What is the output of 6 // -4
Give reason in support of ur answer
-2
In Python, when you use the double forward slash // operator for division, it performs floor division, which means it rounds down the result to the nearest integer. When you perform the operation 6 // -4, it will give you the result of -2, because -1.5 (the exact division result) is rounded down to the nearest integer, which is -2.
What is the output of
~~~
10 - 6 ** 2 / 9 * 10 + 1
~~~
-39
