Python Flow Control : Pass Statement

-
In this article, you'll learn about pass statement. It is used as a placeholder for future implementation of functions, loops, etc.

What is pass statement in Python?

In Python programming, pass is a null statement. The difference between a comment and pass statement in Python is that, while the interpreter ignores a comment entirely, pass is not ignored.
However, nothing happens when pass is executed. It results into no operation (NOP).

Syntax of pass

pass
We generally use it as a placeholder.
Suppose we have a loop or a function that is not implemented yet, but we want to implement it in the future. They cannot have an empty body. The interpreter would complain. So, we use the pass statement to construct a body that does nothing.

Example: pass Statement

We can do the same thing in an empty function or class as well.

def function(args):
    pass

class example:
    pass

Thank you :)

Python Matrix

What is a matrix? A matrix is a two-dimensional data structure. In real-world tasks you often have to store rectangular data table. The table below shows the marks of three students in different subjects. S.No Student Name Science English History Arts Maths 1 Roy 80 75 85 90 95 2 John 75 80 75 85 100 3 Dave 80 80 80 90 95 Such tables are called matrices or two-dimensional arrays. In python any table can be represented as a list of lists (a list, where each element is in turn a list). For example: A = [[ 'Roy' , 80 , 75 , 85 , 90 , 95 ],[ 'John' , 75 , 80 , 75 , 85 , 100 ],[ 'Dave' , 80 , 80 , 80 , 90 , 95 ]] In the above example A represents a 3*6 matrix where 3 is number of rows and 6 is number of columns. How to create a matrix? In python, matrix is a nested list. A list is created by placing all the items (elements) inside a square bracket  [ ] , separated by commas. Example 1

What are the steps involved in the concreting Process?

-

We perform the required procedures to get the space ready for concrete after we inspect the site and provide you an obligation-free price. This may occasionally necessitate a little flattening, excavation, or pier hole digging. Depending on the project, a combination of formwork (wood that shapes the area to be concreted), waterproofing membrane, reo bar or mesh, and styrofoam blocks—which aid in the formation of a stable, structural lattice—will typically be needed. The 5 stages of the concreting process Once the preparations are done for pouring, we proceed with the following 1.Batching : The measurement of materials for making concrete is known as batching. There are two methods of batching: (i)Volume batching  and (ii)Weight batching    Volume Batching :- Due to the challenge it presents in quantifying granular material in terms of volume, volume batching is not a good approach for distributing the material. Compared to the same volume of dry compacted sand, the weight of moist san
