Solution
Here is the Python code that follows the instructions given in the question:
# Importing re library
import re
# Defining the string
mystring = "Hello!! Good Morning, Welcome to python tutorial class 24."
# Using findall() method to find 'e' and 'o' in the string
matches = re.findall('[eo]', mystring)
# Iterating through the list and printing all the occurrences
for match in matches:
print(match, end="")
This code will print all the occurrences of 'e' and 'o' in the given string. The findall() function of the re module returns all non-overlapping matches of pattern in string, as a list of strings. The string is scanned left-to-right, and matches are returned in the order found.
In the regular expression '[eo]', the square brackets define a character set, and 'e' and 'o' are the characters we're looking for. This means the function will return all 'e's and 'o's it finds in the string.
The for loop then iterates over the list of matches, printing each one. The end="" argument in the print() function means that it won't print a newline after each character, so all the characters are printed on the same line.
