Common methods of string ?
find(),replace(), endswith()

Capable to do 60,000 OPS (Operations Per Second
What is type hinting ?
Adding type information to function ,introduced n python 3.5 ,specified in PEP-484
Who Developed Boolean Logic ?
George Boole
What means High Level in Programming Languages ?
High leve means Abstraction , Coding is in English language & easily understandable by humans , Compiler Based
What is OPS ?
Operations Per Second
How many Trasistors are in Intel’s First CPU ?
2300 Transistors
Can string typcasted to int .
yes , only numbers in string , string alphabests are not typcasted to int.
First Intel CPU ?
Intel 4004
It is the first commercial CPU
What means Dynamically typed ?
You dont want to define type of the variable , it automatically understood by value in it.
How to check Truth Value of python object ?
By using bool() method

Strings are mutable or imutable ?
Strings are immutable in Python, which means a string cannot be modified.
You cannot modify the string once created. If you change a string, Python creates a new string with the updated value and assigns it to the variable.
str1 = “first”
id(str1)
str1 = str1+ “ Two”
id(str1)
Output
How to get the character from ASCII number ?
Using chr(number) method
Which method should I use to convert String “welcome to the beautiful world of python” to “Welcome To The Beautiful World Of Python”
title() method
How to convert the string “my name is James bond” to “My name is James bond”
use capitalize() method
What is the output of the following code?
var = “James” * 2 * 3
print(var)
6 times james
JamesJamesJamesJamesJamesJames
What is the Output of the following code?
for x in range(0.5, 5.5, 0.5):
print(x)
Program executed with errors
Can we use the “else” block for for loop?
for example:
for i in range(1, 5):
print(i)
else:
print(“this is else block statement” )
We can use the else block after the end of for loop and while loop. The else block is used to check the successful execution of a loop. If the loop executed successfully without any issues, the else block executes.
What is the output of the following code?
def calculate (num1, num2=4):
res = num1 * num2
print(res)
calculate(5, 6)
30
In Python, we can set default values for arguments. If the function is called without the argument, the default value is used.
What is the output of the following code?
listOne = [20, 40, 60, 80]
listTwo = [20, 40, 60, 80]
print(listOne == listTwo)
print(listOne is listTwo)
True,False
The == (Equal To) operator used to compare the values of two objects and The is operator compares the identity of two objects.
How to Print memory Location ?
use id() method.
What is the Output of this code ?
str1=”Sandy”
str2=”Mohan”
str2=str1
print(id(str1),id(str2))
It print the same memory location
In which version of python type hinting is introduced
Type hinting is introduced in Python 3.5
In which type document type hinting is specified ?
Type hinting is specified in PEP 484 document
Which function is required to get index in for loop
enumerate method
