Python is not language developers aren’t aware of, in fact, it is a programming language almost all developers are working on, be it their project or any clients. This language comprises different functions that also involve operators and operands. While working, **typeerror: unsupported operand type(s) for /: ‘str’ and ‘int’ **is an alarming error that occurs, and developers often look for the correct answer to keep the functions working.

`TypeError: unsupported operand type(s) for /: 'int' and 'str'`

Let’s dig more to find out what makes this error occurs and how to solve it

## What causes the “**typeerror: unsupported operand type(s) for /: ‘str’ and ‘int’**” error?

The prime cause of **typeerror: unsupported operand type(s) for /: ‘str’ and ‘int’** is the division operator “`/`

” when we use it with a number and a string. Whenever the data of any object involves in an operation is inappropriate, typeerror occurs.

Dividing a string and an integer when the data type of object is not compatible, the interpreter of Python shows up the Typeerror.

Let’s take a look at the example

```
a = 99
b = "11"
c = a / b
```

**Output:**

```
Traceback (most recent call last): File "/home/aditya1117/PycharmProjects/pythonProject/string12.py", line 3, in <module>
c = a / b
TypeError: unsupported operand type(s) for /: 'int' and 'str'
```

## How to Solve?

Whenever a division operator is used, it divides the operands, the first one by the second, and then returns the value, which is a float. Take a look at another example with a solution

### Using a function int ()

**Example**

```
a = 99
b = "11"
print(f'a / b = {a / b}')
```

```
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
print(f'a / b = {a / b}')
TypeError: unsupported operand type(s) for /: 'int' and 'str'
```

**Solution**

The easiest and quickest solution is to convert the variable y to an integer by using a function int (). Once you edit, the code will work fine. Let’s check out the revised code

```
a = 99
b = "11"
print(f'a / b = {a / int(b)}')
```

**Output:**

`a / b = 9.0`

Hence, the division or ** typeerror: unsupported operand type(s) for /: ‘str’ and ‘int’** is solved.

### Use float () to convert strings

**Example**

Let’s take a look at a bit complex program to understand the error and solution that includes division as well as multiplication and addition operators

*Take input from the user and calculate the area of a triangle*

```
edge1 = input('Enter the first edge: ')
edge2 = input('Enter the second edge: ')
edge3 = input('Enter the third edge: ')
# calculate the semi-perimeter
p = (edge1 + edge2 + edge3) / 2
# calculate the area
area = (p*(p-edge1)*(p-edge2)*(p-edge3)) ** 0.5
print('The area of the triangle equal ' + str(area))
```

**Output:**

```
Enter the first edge: 9
Enter the second edge: 9
Enter the third edge: 9
Traceback (most recent call last):
File "<string>", line 6, in <module>
TypeError: unsupported operand type(s) for /: 'str' and 'int'
```

**Solution**

In Python, one can’t multiply a string value with a non-integer value. You get an error if multiply a string with a string without converting it to a float or integer.

The possible solution to fix this error is to use `float ()`

to convert strings. Check out the solution code

```
edge1 = float(input('Enter the first edge: '))
edge2 = float(input('Enter the second edge: '))
edge3 = float(input('Enter the third edge: '))
# calculate the semi-perimeter
p = (edge1 + edge2 + edge3) / 2
# calculate the area
area = (p*(p-edge1)*(p-edge2)*(p-edge3)) ** 0.5
print('The area of the triangle equal ' + str(area))
```

**Output:**

```
Enter the first edge: 9
Enter the second edge: 9
Enter the third edge: 9
The area of the triangle equals 35.074028853269766
```

## Conclusion

And there you know how to convert strings to integers or float!

Python programming is fun if you know the trick to solve the typeerrors. I hope with the help of the examples and solutions to convert the data type, you will crack the right code in your next programming.

With this, I wish you happy coding!
