In Python, both re.search() and re.match() are used for pattern matching using regular expressions, but they differ in how they operate:
re.match():
Checks for a match only at the beginning of the string.
If the pattern is not found at the start, it returns None.
re.search():
Scans through the entire string to find the first occurrence of the pattern.
It can find matches even if the pattern is not at the beginning.
Use re.match() when you want to ensure the pattern is present at the start of the string, and re.search() when the pattern can appear anywhere in the string.
