Write a function that will randomly upper and lower characters in a string - `randomCase()` (`random_case()` for Python).
A few examples:
```
randomCase("Lorem ipsum dolor sit amet, consectetur adipiscing elit") == "lOReM ipSum DOloR SiT AmeT, cOnsEcTEtuR aDiPiSciNG eLIt"
randomCase("Donec eleifend cursus lobortis") == "DONeC ElEifEnD CuRsuS LoBoRTIs"
```
Note: this function will work within the basic ASCII character set to make this kata easier - so no need to make the function multibyte safe.
import random

def random_case(x):
    result = ""
    
    for c in x:
        if random.randint(0, 1) == 1:
            result += c.upper()
        else:
            result += c.lower()
    
    return result
import random

def random_case(x):
    result = ""
    
    for c in x:
        if random.randint(0, 1) == 1:
            result += c.upper()
        else:
            result += c.lower()
    
    return result
