Previous exercises, we created this function:

```>>> def string_length(mystring):
...    return len(mystring)
```

Calling the function with a string as the value for the argument mystring will return the length of that string.

If an integer is passed as an argument value:

string_length(10)

that would generate an error since the len() function doesn’t work for integers.

We have to modify the function so that when an integer is passed as input, the function should output a message like “Sorry integers don’t have length.”

So, How we do it?

```>>> def string_length(mystring):
...    if type(mystring) == int:
...        return "Sorry, integers don't have length"
...    else:
...        return len(mystring)
...
>>> string_length(10)
"Sorry integers don't have length."
```

That’s it!

Create a function that takes any string as an argument and returns the length of that string.

So, the code is:

```>>> def string_length(mystring):
...    return len(mystring)
...
>>> print(string_length("Hello"))
5
```

Create a function that converts Celsius degrees to Fahrenheit. The formula to convert Celsius to Fahrenheit is F = C × 9/5 + 32.

Here goes the code:

```>>> def cel_to_far(celsius):
...   fahrenheit = celsius *9/5+32
...   return fahrenheit
...
>>> print(cel_to_far(10))
50.0
```

That’s it. here you go!
