Do you know what is Sum in Python? Have you ever thought about what does sum do in Python? Let us try to gain some knowledge about summing in Python. Also, we will try to know how to sum in Python.
But before we know how to sum in Python & what does sum do in Python, let us gain some knowledge about summing in Python. Let us try to assume one real-life scenario. This will help to understand sum in Python.
Let us assume one scenario.
Suppose, you are a kindergarten student. Your teacher provides you with one assignment that you need to complete. The assignment is to add some random numbers. And on the next day, you have to provide the answer to your teacher. Random numbers may vary from ten to ten thousand. As a kindergarten student, you might face this issue. What will you do in such cases? Will you not be able to complete the question?
Well, in this type of case, you might need to take help from your mother or father. At that age, it is not possible to use the calculator. And the use of the programming language at that age will be daydreaming. So, with the guidance of your parents, you can able to complete the task.
Though, you will not face this challenge while you are learning a programming language. As you can able to use at least the calculator. So, this will not be assumed as an issue for you. But the sum function will help you in this case.
Summing in Python is just like taking help from your parents. Your parents guide you to find the answer to the summation. Summing in Python will directly provide you with the answer. We will find out more about it. But first, let us know what is sum in Python. This will also help to get the answer of what does sum do in Python.
What Is Sum In Python:
The sum is a function in the Python programming language. It is a built-in function for the Python programming language. The main objective of this function is to provide a summation of a list of numbers. You sometimes use for loop to get this type of answer. But Python is more robust programming language ever. This is the programming language that is being used for developing some big projects. So, for that Python should reduce the burden of the programmers.
The sum in Python is associated with the list in Python programming language. The elements that are inside of a list should be added for the necessity of the program. For that purpose, you need to use each loop there. In that case, every element inside the list will get added by the starting number. This will take a lot of time. And if the numbers inside of the list are hundreds, then the time consumption will be huge. To reduce time consumption, you can use this function. This will reduce the program length to a very small size.
How To Sum In Python:
The sum in Python is an inbuilt function. Like all the functions, sum() also has some parameters. These are called arguments. The first argument of the sum() function will be the list name. You need to provide the list name of the first argument. As the second argument, you need to provide the starting variable. The starting variable is a variable that indicates the base value. If you don’t provide any number there, then the program will assume the start value as zero. And it starts its operation.
So, the process to sum in Python can be done in two ways. These ways will depend upon the declaration of the starting variable. So, the paths will be:
- Sum Function Without Start Parameter
- Sum Function With Start Parameter
Sum In Python Without Start Parameter:
Here, we have declared one list first. Also, we have declared the list & provided values to it. Then programmers need not do more operations. They will simply declare one variable. Then the sum function will be assigned to the variable. As in this case, there will be no starting variable. So, only the list name will be transferred there. The sum() function will do its operation. And the result will be stored in the variable. Then programmers can print the value of the declared variable. As here, the starting variable is undeclared, so it will be zero by default. So, it will simply provide the added value as the answer.
General Syntax: Sum(list-name)
Example:
CodingZap = [10,20,30,40] # List Of Numbers ZapOne = sum(CodingZap, 20) # Sum Function With Start Parameter 20 print("Sum Function With Start Parameter: ", ZapOne)
Let us try to find the output of the above code. This will help to understand the sum in Python process.
Output:
Sum In Python With Start Parameter:
Now, in this case, also, we have to declare one list. Along with that, we have to provide value to the list. Then we will directly call the sum() function. In the same process, we will declare one variable. In that variable, we need to assign the sum() function value. But here, is another argument, we need to share. Here, we need to provide the start argument. Here, the start argument is 20. So, after providing the name of the list, we need to write the start variable name. So, it will add the values to the list. And at last, it will add the starting variable value to the answer. We can print the answer in the same process.
General Syntax: Sum(list-name, Starting-Variable)
Example:
CodingZap = [10,20,30,40] # List Of Numbers ZapOne = sum(CodingZap, 20) # Sum Function With Start Parameter 20 print("Sum Function With Start Parameter: ", ZapOne)
Let us try to find the output of the above code. This will help to understand the sum in Python process.
Output:
Conclusion:
As we saw, it is very important to know sum in Python programming language.
We need to clarify the concept of what does sum do in Python. Also, along with that, we need to practice how to sum in Python more & more.
It is advisable to clear the basics of the Python programming language. This will help to understand the topic in a better way. This will help us a lot in the future.
