14. What is lambda in Python? Why is it used? Lambda functions are also referred to as a “single-line function.” Here are a few characteristics of a lambda function: It is also known as anoynymous / nameless
Indentation is required in Python. It designates a code block. An indented block contains all of the code for loops, classes, functions, and so on. The most common method is to use four space characters. If your code is not indented properly, it will not run correctly and will generate ...
11. What are lambda functions? 12. How are Dictionaries implemented in Python? 13. Describe the difference between a shallow copy and a deep copy 14. Describe generators in Python and give a brief example of how to use them 15. What is the main difference between a tuple and a list in...
These functions have their local namespace and don’t have any access to variables other than those in their perimeter list and those in the global namespace. Examples: x = lambda i,j: i+j print (x(7,8)) Output: 15 Yet another important question in this list of Python data science ...
To keep things simple for you, you should just know that lambda functions are anonymous functions that are constructed at runtime. Considering that that piece of code can just serve as an indication for you, you can just ignore it and focus on x*x. You see that this function takes one ...
Shallow copies can be created using the copy() method or the copy module in Python. import copy original = [[1, 2], [3, 4]] shallow_copy = copy.copy(original) shallow_copy[0][0] = 9 # Changes the original list as well On the other hand, a deep copy creates a new object ...
9. Explain about the Python Functions? A function in Python is a block of reusable code that performs a specific task. In Python, functions are defined using the “def” keyword, followed by the function name, and a set of parentheses that may include parameters. The function body is inden...
33. What is the difference between formulas and functions in Excel? Formulas are defined by the user and used to calculate certain results. Formulas are either simple or complex and can consist of values, functions, defined names, etc. A function, on the other hand, is a built-in piece ...
Here are 25 PCEP questions focusing on the “KeyboardInterrupt” exception from Python's built-in exception hierarchy. The questions use various formats, including single- and multiple-select questions, fill-in-the-gap, code fill, code insertion, sorting, and more. ...
• Functions in Python are first-class objects. This means that you can assign them to a variable. Python functions can also return other functions or accept them as parameters. • Python is a general-purpose language, which is very popular in many industries. Developers use it in automati...
