Correct option is B
The
partition() method in Python always splits a string into
three parts: the part before the separator, the separator itself, and the part after the separator. If the separator is not found, it returns the original string as the first part, and the other two parts are empty strings.
Important Key Points:
1.
Always 3 Parts: The partition() method always returns a tuple of three elements, no matter what.
2.
Separator-based Split: It splits the string at the first occurrence of the separator.
3.
Tuple Structure: The returned tuple contains three values: the part before the separator, the separator itself, and the part after the separator.
4.
No Separator Found: If the separator is not found, the entire string is returned as the first element of the tuple, and the other two elements are empty strings.
5.
Immutable: The original string is not modified, and the split is done based on the first occurrence of the separator.
Knowledge Booster:
·
Option (a): There is no break method in Python for strings. break is a control statement used in loops, not a string method.
·
Option (c):
mid is not a string method in Python. It is sometimes used in other languages to refer to extracting a substring, but it does not exist as a built-in method in Python.
·
Option (d): The
split() method splits a string into multiple parts based on the separator, but unlike partition(), it does not guarantee exactly three parts. It can split a string into more or fewer parts depending on the number of occurrences of the separator.
