Data Types – Tuples, Strings Use Case – Where we need to store data that will stay the same. Example – Python Copy Code Run Code 1 2 3 4 5 6 tuple1 = ("a", "b", "c", "d") # modifying element: tuple1[2] = "g" # Should give an error # tuple object does not...
The # character is used to start comments in Python. However, docstrings are also used to comment (strings enclosed within triple quotes). Consider the following scenario: In Python, comments begin with a #. print(“Comments in Python begin with a #”) Output: Python comments begin with a ...
Slicing can be done on strings, arrays, lists, and tuples. numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] print(numbers[1 : : 2]) #output : [2, 4, 6, 8, 10]5. What is docstring in Python? Documentation string or docstring is a multiline string used to document a spec...
This is another crucial Python interview question asked in technical interviews at top companies. Slicing in Python is primarily used to access some parts of sequences such as strings, tuples, or lists. Q20. What are Literals in Python? Literals in Python are used to represent fixed values f...
Explanation: In Python, sets do not support the + operator because they are unordered collections of unique elements, and + is meant for operations like concatenation (used with lists and strings). 14. What will be the output of the following Python code?

Below is a set of questions for the Certified Entry-Level Python Programmer (PCEP) examination focusing on "constructing strings." The questions use various formats, including single- and multiple-select questions, fill-in-the-gap, code fill, code insertion, sorting, and more. ...
What are Python's dictionaries? Python's dictionaries are kind of hash table type. They work like associative arrays or hashes found in Perl and consist of key-value pairs. A dictionary key can be almost any Python type, but are usually numbers or strings. Values, on the other hand, can...
Strings frozenset() Tip: don’t believe us on our word! Try it out for yourself below and experiment in the IPython shell :) Note that, as you’re working with hashable items, checking membership (testing whether a certain element is part of your sequence) will go faster with sets th...
6. What are the built-in data types in Python? Python has several built-in data types, including integers, floating-point numbers, complex numbers, strings, lists, tuples, sets, and dictionaries. These data types are used to store and manipulate different types of data in Python. ...
