To calculate percentage, there are some solutions we have effectively tested. Let’s follow this article, it will help you learn about how to calculate percentage in Python.

## How to calculate percentage in Python

In Python, there is no percent operator to calculate percentages, but alternative ways exist. To calculate percentage, we have the following ways:

### Use the division operator to combine the multiplication operator

You can use the division operator to get the quotient and multiply that quotient by 100 using the multiplication operator to get the result as a percentage.

**Example:**

- Initialize two variables containing integers.
- Use the division operator to get the quotient.
- Use the multiplication operator to multiply the quotient by 100, which returns a percentage.

myNumber1 = 1 myNumber2 = 2 # Use operator (/) to get quotient quotient = myNumber1 / myNumber2 # Use operator (*) to multiply the quotient by 100 percent = quotient * 100 print('The percentage is:', percent)

**Output:**

`The percentage is: 50.0`

**Use f-string**

New built-in string formatting method from Python 3.6 in the following syntax:

`f'a{value:pattern}b`

‘

**Parameters:**

**f character:**use the string f to format the string.**a,b:**characters to format.**{value:pattern}:**string elements need to be formatted.**pattern:**string format.

**Example:**

- Initialize two variables containing integers.
- Use the division operator to get the quotient.
- Use f-string to format the quotient as a percentage.

myNumber1 = 1.0 myNumber2 = 2.0 quotient = myNumber1 / myNumber2 # Use f-string to format the quotient as a percentage print(f'The percentage is: { quotient:.0%}')

**Output:**

`The percentage is: 50%`

**Use the format() method**

You can use the format() method. The format() method returns the formatted result of a given value specified by the specified formatting.

**Syntax:**

`format(value[, format_spec])`

**Parameters:**

**value:**value to be formatted.**format_spec:**format you want to use for ‘value’.

**Example:**

- Initialize two variables containing integers.
- Use the division operator to get the quotient.
- Use the format() function to format the quotient as a percentage.

myNumber1 = 1.0 myNumber2 = 2.0 quotient = myNumber1 / myNumber2 # Use the format() function to format the quotient as a percentage percent = "{:.1%}".format(quotient) print('The percentage is:', percent)

**Output:**

`The percentage is: 50.0%`

**Create a custom function to calculate percentage**

You can create a custom function to calculate the percentage if you want.

**Example:**

def percentage(a, b): try: # Multiply the quotient by 100 to get the percentage result percentage = 100 * float(a) / float(b) return str(percentage) + "%" except ZeroDivisionError: return 0 print("The percentage is: ", percentage(1, 2))

**Output:**

`The percentage is: 50.0%`

The fractional function will output a string value.
