In what cases do you use the str() function?

str() is used to generate a 'human readable string expression' for an object in python. Say for example , we have the following class in python: class Person: def __init__(self,name,age): self.name = name self.age = age print(Person('Anon',30)) This prints <__main__.Person object at 0x7f12b3fc7400> Which is a pointer to the memory address , not very helpful to comprehend. On the other hand , class Person: def __init__(self,name,age): self.name = name self.age = age def __str__(self): return f"Name:{name} Age:{age}" print(Person('Anon',30)) will print Name:Anon Age:30 which is more human readable ( kinda). The same thing happens with int - it has an inbuilt __str__ method which parses the input and converts it into a human readable string ( using ASCII/UTF-8 conversion or whatever). If you are still interested , I'd recommend going and reading up on __repr__ , which is similar to __str__ but is intended to be used via debugging rather than returning a string representation. Tbf , you can get around this using fstrings .... More on reddit.com

What does __str__ method do?

Yeah, it's just so you can print it. If you try to print a variable that is not a string it won't know what to do, so when you make a __str__ method it's like saying "If I tell you to print this variable, this is how I want you to do that" More on reddit.com

Python Strings | Python Education | Google for Developers

Characters in a string can be accessed using the standard [ ] syntax, and like Java and C++, Python uses zero-based indexing, so if s is 'hello' s[1] is 'e'. If the index is out of bounds for the string, Python raises an error.

Negative numbers also work within [ ] and slices: -1 is the last char in the string, and -2 is the next to last char, and so on. So for example with s = 'Python', s[-1] is 'n' and s[-2] is 'o'. This is convenient when you want to refer chars near the end of the string, and it works in slices too.

Title. I know you use it for integers, but in what context? Also, is it used for anything else?

str() is used to generate a 'human readable string expression' for an object in python. Say for example , we have the following class in python: class Person: def __init__(self,name,age): self.name = name self.age = age print(Person('Anon',30)) This prints <__main__.Person object at 0x7f12b3fc7400> Which is a pointer to the memory address , not very helpful to comprehend.

If you want to convert anything to a string. Any integers, floats, lists, any object that implements __str__() really. I believe when you print something, it converts it to a string. So if you want a string, thats what str() is for

r/learnpython on Reddit: What does __str__ method do?

November 14, 2020 -

I'm still a beginner in python and my English is not really good, so I may have a little bit of understanding the explanation given in my course.

So I have this code:

class Apple:
    def __init__ (self,color,flavor):
        self.color=color
        self.flavor=flavor
        
    def __str__(self):
        return "This apple is {} and its flavor is {}".format(self.name,self.flavor)
        
jonagold=Apple("red","sweet")
print(jonagold)

The only purpose I see in using the __str__ method, I don't have to write the method in the print () line. If I changed the __str__ method with:

def say(self):
    return "This apple is {} and its flavor is {}".format(self.name,self.flavor)

I would just need to type

print(jonagold.say())

And I would get the same answer. What are the other purpose of using __str__? In what situation would I need to use the __str__?

Thank you :)

Yeah, it's just so you can print it. If you try to print a variable that is not a string it won't know what to do, so when you make a __str__ method it's like saying "If I tell you to print this variable, this is how I want you to do that"

From what I understand __str__ defines how an object of the class will be converted to a string. So like when you’re printing or if you did str(jonagold) Theoretically you could make your own method instead of using __str__ but it’s sort of pointless and isn’t as nice. Like would you rather do print(jonagold) or print(jonagold.say()) ? The second one has more ways it can go wrong especially if someone else is trying to use your class
