What does ## mean in Python?
I have looked at other questions about this and the general consensus seems to be that ## is used for commenting out code. However, in the Interactive Editor for Python, prefixing a line with ## appears to make a sort of section header for the code.
What is the += in Python?

How do you write symbols in Python?

What does i += 1 mean in Python?
The operator is often used in a similar fashion to the ++ operator in C-ish languages, to increment a variable by one in a loop ( i += 1 ) There are similar operator for subtraction/multiplication/division/power and others: i -= 1 # same as i = i – 1 i *= 2 # i = i * 2 i /= 3 # i = i / 3 i **= 4 # i = i ** 4.
What does index += 1 mean in Python?
index =+ 1 means, index = index + 1. If we want to reach that point we need to bring the ‘index’ value to that level by adding 1 in every iteration by index =+ 1.
What does == mean in Python?
The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory. In the vast majority of cases, this means you should use the equality operators == and !=
What does find () mean in Python?
Definition and Usage The find() method finds the first occurrence of the specified value. The find() method returns -1 if the value is not found. The find() method is almost the same as the index() method, the only difference is that the index() method raises an exception if the value is not found. (
What is the main method in Python?
The Python main method is not necessarily a method as per the technical meaning of the term, albeit it acts as an entry point for your program, which sort of mimics the function of a main method — no pun intended — in the languages that actually use one.
