@driscollis Answer C

Enumerate is used for index
So, the key will be the index 01,2,3,4
The value is the letters a,b,c,d,e

So, C is the right answer

[Muhammad Hunain @Hunain_5698]

@Python_Dv Two sets can't concatenate by using+ operand

So, C is the right answer

[Muhammad Hunain @Hunain_5698]

@Python_Dv Answer B

List comprehension method
For loop means iterate through numbers in list and check for even numbers because (if x%2==0)

So 2 and 4 are the numbers
Now x*x means
2*2=4
4*4=16

So, B is the right answer

[Muhammad Hunain @Hunain_5698]

@Python_Dv Answer D)

1. In line one str1 is a variable equal to a string "6/4"
2. In line two print('Str1') the Str1 is in quotation means not the same variable as in line one
So, the output will be Str1

In short,
Print(Str1) the output will be 6/4
Print ('Str1') the output is Str1

@Python_Dv x=3
y=4
Then y=5, the new value of y will replace the previous one
So, y=5
z=6

3+5+6=14

So, B is the right answer

[Muhammad Hunain @Hunain_5698]

@Python_Dv str1 = 'abc'
str2 = str1
means str2='abc'

Now, str1+='d'
means str1='abcd'

Where str2 remains unchanged

str1 is str2 means 'abc' is 'abcd'
Which returns false

So, B is the right answer

@clcoding If parameters having values by default and not pass the argument then those values will print out when invoking the function

But if having default parameters and also passing the value as a argument the argument value will be preferred

So, A is the right answer

[Muhammad Hunain @Hunain_5698]

@Python_Dv Spli.t method split guven string with assigned element and returns a list

In rada remove 'a' from radar and return the remaining variables in a list

So, A is the right answer

[Muhammad Hunain @Hunain_5698]

@Python_Dv In python ** represents exponent or power
Square of 11=121
Cube of 2=8
121+8=129

So, A is the right answer

[Muhammad Hunain @Hunain_5698]

@Python_Dv Swapcase will change the lower case into upper case

So, A is the right answer

[Muhammad Hunain @Hunain_5698]

@CarlAODonaill @Python_Dv Yes

@clcoding Invoke hamster class which inherits animal class
Super method will print very
And the small will be printed out

The output will be very small

[Muhammad Hunain @Hunain_5698]

@Python_Dv Join method in python join the list elements with given delimiter
''.join(L) means join elements in list L without space between them

So, C is the right answer

[Muhammad Hunain @Hunain_5698]

@clcoding This is based on Method overriding concept

Calling car(), the method printconsumption is not defined in child class so it will move to parent class and
Print "low"

Invoking truck() the method is there, the output will be "high" for truck()

The final output will be
Low
High

[Muhammad Hunain @Hunain_5698]

@clcoding Second element of list at index position 0
The output will be 2
So, B is the right answer

[Muhammad Hunain @Hunain_5698]

@Python_Dv B is the right answer
