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.
