// operator use in python

Comment

#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)

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)")
