+# PERCENTAGE CALCULATOR :heavy_division_sign:
+
+### The function Percentage calculator asks the user for their marks in 5 subjects, calculate the percentage, and prints the result and provide the result in a Percentage_output.txt file.
+
+* Inside the function, we first initialize two variables: `total_marks` and `obtained_marks.` `Total_marks` represents the total number of marks that can be obtained for the 5 subjects, and `obtained_marks` represents the number of marks the user has obtained. We set `total_marks` to 0 and `obtained_marks` to 0 at the beginning, since no marks have been obtained yet.
+
+* Next, the program uses a for loop to iterate over the 5 subjects. For each subject, the user is prompted to enter their marks using the `input` function. The program then converts the user's `input` to an integer using the `int` function, since the `input` function returns a string.
+
+```python
+total_marks = 0
+subject_list = ['Maths','Hindi','English','Sst','Science']
+
+for subject in subject_list:
+    marks = float(input(f"Inset the mark of {student_name} in subject {subject}: "))
+    total_marks total_marks + mark
+    file_write.write(str(f"  {subject}_{marks}\n"))
+```
+
+* After the marks have been obtained, the program adds 100 to the `total_marks` (since each subject is worth 100 marks) and adds the user's marks to `obtained_marks`. This allows us to keep track of the total number of marks available and the number of marks the user has obtained.
+
+* After the for loop finishes, the program calculates the percentage by dividing `obtained_marks` by `total_marks` and multiplying the result by 100. This gives us the user's percentage as a decimal.
+
+* Finally, the program prints the percentage to the user using the `print` function and the `f` string format. The `f` string allows us to embed the value of the `percentage` variable directly into the string, so that the user can see their percentage.

+## INSTALLATION INSTRUCTIONS
+### The easiest way to install this Percentage calculator:
+1. Install [`Python compiler`](https://www.python.org/downloads/) :snake: on your local machine.
+2. Clone this project or download this repo.
+3. Delete all content of `Percentage_output.txt.`
+4. Fire :fire: or run this command in bash to install a `External module` called [`Play sound.`](https://pypi.org/project/playsound/)
+```bash
+pip install playsound
+``` 
+3. And you are good to go
