obtains a specified bitstring in python

To obtain a specified bitstring in Python, you can use bitwise logical operators and string manipulation. Here's an example:

main.py
# define a binary number as a string
binary_num = "10101010"

# extract a specified bit string
start_position = 2
end_position = 6
specified_bitstring = binary_num[start_position:end_position]

print(specified_bitstring)  # output: 1010
237 chars
10 lines

In this example, we start by defining a binary number as a string "10101010". We then define the starting and ending positions of the specified bitstring using the variables start_position and end_position.

Using Python's string manipulation capability, we extract the specified bitstring by slicing the binary number string using the provided start and end positions. The resulting specified bitstring is stored in the specified_bitstring variable: "1010" in this case.

This approach uses simple string manipulations, and can be easily modified to extract bitstrings of different sizes, from different positions within a binary number string.
