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.
The image in the photograph is representing A. Analog Data. Analog data is data that is represented in a physical way. Where digital data is a set of individual symbols, analog data is stored in physical media, whether that's the surface grooves on a vinyl record, the magnetic tape of a VCR cassette, or other non-digital media. Analog and digital signals are different types which are mainly used to carry the data from one apparatus to another. Analog signals are continuous wave signals that change with time period whereas digital is a discrete signal is a nature. Examples of analog technology: photocopiers. old land-line telephones. audio tapes. old televisions (intensity and color information per scan line). Analog and digital signals are the types of signals carrying information. The major difference between both signals is that the analog signals that have continuous electrical signals, while digital signals have non-continuous electrical signals.
Answer: All the above questions should be asked
