Why this code isn't giving any error

Question

I made this code today :
def func(x,y) :
print("Hello World")
return(x+y)
z = int(func(3,4))
print(z)

As you can see I have made a function which prints a string and returns a value together. Now shouldn't it give an error when I used int function to turn it to an integer? But it isn't giving any error
Please explain how is it happening

Answer 1

Arin In the code you shared, the 'func' function prints the string "Hello World" and then returns the sum of the input values 'x' and 'y'. The returned value is assigned to the variable 'z'. You then attempt to convert 'z' to an integer using the 'int()' function.

The reason you're not seeing an error is because the 'print()' statement inside the 'func' function doesn't affect the return value or the behavior of the 'int()' function. The 'print()' function simply displays the string "Hello World" on the console when the 'func' function is called, but it doesn't interfere with the return value.

When you call 'int(func(3, 4))', the 'func' function is executed, "Hello World" is printed, and the sum of '3' and '4' (which is '7') is returned. Then, the 'int()' function is applied to '7', which doesn't cause any error because '7' is already an integer.

In summary, the 'print()' statement inside the function doesn't affect the return value or the conversion to an integer. It only displays a message to the console

Answer 2

My AI said me that:
The code you provided doesn't raise any errors because the string "Hello World" is printed before the return statement, and the return value of the function is the result of the addition operation (`x+y`), which is an integer. When you call `int(func(3,4))`, it executes the function `func(3,4)` which prints "Hello World" and returns the sum of 3 and 4, which is 7.

The `int()` function is then applied to the return value of the function, converting it to an integer. Since the return value is already an integer, there is no error. The converted value, 7, is assigned to the variable `z`, and it is then printed.

In Python, you can convert a numerical string representation to an integer using the `int()` function. If the string cannot be converted to an integer, a `ValueError` will be raised. However, in your code, there is no situation where the `int()` function encounters a string that cannot be converted to an integer, so no error is raised.

In summary, the code executes without errors b

Answer 3

It won't give error because print will simply print the statement you are reusing returned values not print statement value

Answer 4

When u call function first print will be executed it will print hello world then u returning value and it assigned to z then it will print the value of z

Fꫀⲅძ᥆͟ᥙ᥉᯽ ok thanks
Can you pls tell me which AI did u use?

Answer 6

AS Raghuvanshi I see
And just for clarification I want to ask one more question
Does the print("Hello World") function execute while reading the variable z?

Answer 7

AS Raghuvanshi oh thanks
Now i have understood the concept fully

Hola soy nuevo ayudaaaa

Hi, check this:
a = "test"
print(a)
print(str(a)) # no Error as well. So seems like turning to a string/integer smth that's a string/integer already is a bit excessive - at least here as well as in your example, but can imagine the situation it would be ok, e.g. when taking various user input.
