Class

Question

Can someone explain this code to me?

class SpecialString:
def __init__(self, cont):
self.cont = cont

def __truediv__(self, other):
line = "=" * len(other.cont)
return "\n".join([self.cont, line, other.cont])

spam = SpecialString("spam")
hello = SpecialString("Hello world!")
print(spam / hello)

Answer 1

# You can of course do the same with an ordinary function.

def my_owndiv(str_A, str_B):
line = "=" * len(str_A)
return "\n".join([str_A, line, str_B])

str_A = "spam"
str_B = "Hello world!"
print(my_owndiv(str_A, str_B))

# Here, the string join method put a newline character \n
# between every string element in the list [str_A, line, str_B]

Hi, Artin !

This code redefines how the division operator / works for instannces of your SpecialString class, making it behave in your own way.

Instead of dividing, it creates a separation betwen the two strings, with a line of = characters.

It’s an example of operator overloading. Makes it possible to customize the operators behavor.

I did not understand this line in particular

return "\n".join([self.cont, line, other.cont])
