Write a Python program to replace at most 2 occurrences of space, comma, or dot with a colon. Hint: use re. sub(regex, "newtext", string, number_of_occurences)

Explanation:

The "re" module in python provides various functions to perform complex string operations easily.

For example, you can check whether a specific word exists in a given string or to replace it with some other word.  

Some of the functions in the re module are:

re.findall

re.search

re.sub()

We are particularly interested in the re.sub() function, we can use this function to replace the occurrences of space, coma or dot with semicolon.  

Syntax:

re.sub(pattern, replace, target_string, n).  

Where pattern = space, coma or dot  

replace = semicolon  

target_string = any string containing spaces, coma and dots

n = number of times you want the replacement to be done  

Code:

import re  

target_string = "Hello world,code,code."  

replace = ":"

pattern = "[ ,.]"

print(target_string)

print(re.sub(pattern, replace, target_string, 2) )

Output:

Hello world,code,code.

Hello:world:code,code.

It replaced the first white space and coma with semicolon, if we increase the n to 4 then the output is

Hello:world:code:code:

As expected, it replaced all of the space, coma, and dots with semicolons.

the answer is b) 2nd

hope this and plz mark as brainliest!

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
