#One thing to note- since Python treats all numbers as floats (decimal numbers),
#you can use the double division sign // to get an integer.
#This is useful for finding indexes.
string1 = "abcde"  
middle = string1[len(string1) // 2]  # 4//2
print(middle)

|= operator python

Comment

>>> s1 = {"a", "b", "c"}
>>> s2 = {"d", "e", "f"}

>>> # OR, | 
>>> s1 | s2
{'a', 'b', 'c', 'd', 'e', 'f'}
>>> s1                                                     # `s1` is unchanged
{'a', 'b', 'c'}

>>> # In-place OR, |=
>>> s1 |= s2
>>> s1                                                     # `s1` is reassigned
{'a', 'b', 'c', 'd', 'e', 'f'}

what is the ^ operator in python

Comment

the ^ operator in python is xor logical operation 

if you dont know what xor is
basicly its a bitwise operator 
which is some logic that is done on each bit of the data 

side note:(if you dont know any thing about binary or logic on them 
i suggest you learn about the topic its not easy to explain here)

the xor have 2 parameters a and b 
here is what happens on each bit of a and b
a|b|result
0|0|0
1|0|1
0|1|1
1|1|0

python := operator

Comment

-1

There is new syntax := that assigns values to variables as part of a larger expression. It is affectionately known as “the walrus operator” due to its resemblance to the eyes and tusks of a walrus.

if (n := len(a)) > 10:
    print(f"List is too long ({n} elements, expected <= 10)")
