I"m used that in Objective-C I"ve got this construct:
- (void)init {
if (self = [super init]) {
// init class
}
return self;
}
Should Python also call the parent class"s implementation for __init__?
class NewClass(SomeOtherClass):
def __init__(self):
SomeOtherClass.__init__(self)
# init class
Is this also true/false for __new__() and __del__()?
Edit: There"s a very similar question: Inheritance and Overriding __init__ in Python

How can I make a time delay in Python?
5 answers
I would like to know how to put a time delay in a Python script.
Answer #1
import time
time.sleep(5) # Delays for 5 seconds. You can also use a float value.
Here is another example where something is run approximately once a minute:
import time
while True:
print("This prints once a minute.")
time.sleep(60) # Delay for 1 minute (60 seconds).
Answer #2
You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.
from time import sleep
sleep(0.1) # Time in seconds

How do I delete a file or folder in Python?
Answer #1
os.remove()removes a file.os.rmdir()removes an empty directory.shutil.rmtree()deletes a directory and all its contents.
Path objects from the Python 3.4+ pathlib module also expose these instance methods:
pathlib.Path.unlink()removes a file or symbolic link.pathlib.Path.rmdir()removes an empty directory.

I was preparing for my coding interview, thanks for clarifying this - Should __init__() call the parent class”s __init__()? in Python is not the simplest one. Will use it in my bachelor thesis

Simply put and clear. Thank you for sharing. Should __init__() call the parent class”s __init__()? and other issues with imp Python module was always my weak point 😁. I just hope that will not emerge anymore
