Why does the splice need two backslash "//" instead of one (ex: "/")?

Not sure why the 2nd backslash is needed? Having a hard time understanding the syntax.

sillycase.py 
def sillycase(string):
    return string[:len(string)//2].lower() + string[len(string)//2:].upper()
    """return string[:len(string)/2].lower() + string[len(string)/2:].upper()"""

The / operator will always return a float. The // operator will return an int

print(4 / 2)   # prints 2.0
print(4 // 2)  # prints 2

print(5 / 2)   # prints 2.5
print(5 // 2)  # prints 2
