Answer:
D. Change the def to def area (width, height = 12)
Explanation:
Required
Update the function to set height to 12 when height is not passed
To do this, we simply update the def function to:
def area (width, height = 12)
So:
In boxlarea = area (5,2), the area will be calculated as:
In box2area = area (6), where height is not passed, the area will be calculated as:
Flip bit position 5 to accomplish this. This maps to hex value 0x20, where the least significant bit is assumed to be at position 0.
Example: ascii "A" = 0x41, "a" = 0x61. 0x41 xor 0x61 = 0x20.
You would implement a flip function by XOR'ing the character value with 0x20.

Explanation:
A computer keyboard is an input device that allows a person to enter letters, numbers, and other symbols (these are called characters in a keyboard) into a computer. Using a keyboard to enter lots of data is called typing. A keyboard contains many mechanical switches or push-buttons called "keys".
Answer:
The program to this question as follows:
Program:
def lettersOnly(s): #defining method lettersOnly
val="" #defining string variable that return value
for i in s: #defining loop to calculate value
if(i.isalpha()): #check condition that value is string
val=val+ i #add value
return val #return value
print(lettersOnly("data3base_ro1c3k5s")) #call method and print value
Output:
databaserocks
Explanation:
In the above python code, a method lettersOnly is declared that accepts a string variable "s" in its parameter. Inside the method, a string variable "val", and loop is declared, in which the "val" variable holds method return value.
- In the loop and if block is used that uses "isalpha" string method, which checks the check alphabetic character in the given value. if this is true it will calculate all value in "val" variable and return its value.
- At the last, the print method is used, which calls the lettersOnly method and prints its return value.
