What is a function in Python?
A function is a block of organized, reusable code that is used to perform a single, related action. As you already know, Python gives you many built-in functions like print(), etc. but you can also create your own functions. These functions are called user-defined functions.
What are attributes in python?

- We can pass multiple arguments to a python function by predetermining the formal parameters in the function definition.
- We can pass multiple arguments to a python function without predetermining the formal parameters using the below syntax: def functionName(*argument)
What is the correct way to call a function in Python?

Can you split a list Python?
Split the list in half. Call len(iterable) with iterable as a list to find its length. Floor divide the length by 2 using the // operator to find the middle_index of the list. Use the slicing syntax list[:middle_index] to get the first half of the list and list[middle_index:] to get the second half of the list.
What is the main function in Python?

You can then refer to the full set of command-line arguments, including the function name itself, by referring to a list named argv. In either case, argv refers to a list of command-line arguments, all stored as strings.
How do you split a sublist in Python?
We just split the strings fetching the sublist using the loop in list comprehension using split function. This task can also be performed using the combination of above 3 functions.
How do you yield in Python?
yield is a keyword in Python that is used to return from a function without destroying the states of its local variable and when the function is called, the execution starts from the last yield statement. Any function that contains a yield keyword is termed as generator. Hence, yield is what makes a generator.

What is chunk in Python?
Advertisements. Chunking is the process of grouping similar words together based on the nature of the word. In the below example we define a grammar by which the chunk must be generated. The grammar suggests the sequence of the phrases like nouns and adjectives etc.
Why generators are used in Python?
Generator comes to the rescue in such situations. Python generators are a simple way of creating iterators. All the work we mentioned above are automatically handled by generators in Python. Simply speaking, a generator is a function that returns an object (iterator) which we can iterate over (one value at a time).
How do you split a list into groups in Python?
Python | Splitting a List into evenly sized Chunks
- Using list comprehension. When working on simpler tasks, this is recommended, but if the requirement is for a bigger application, it is recommended to use methods and encapsulate these tasks inside the methods.
- Using user-defined method.
- Using itertools.
- Using lambda and islice.
- Using a lambda function.
