bytes, or bytearray instance representing an integer literal in the given base. The literal can be preceded by '+' or '-' and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal....
When initializing aCounterobject, you can pass an iterable (such as a list, tuple, or string) or a dictionary as an argument. If an iterable is provided,Counterwill count the occurrences of each unique element in the iterable. We can access the count of a specific element using indices, ...
The count() method The count() method returns the number of non-overlapping occurrences of a given subsection in ByteArray. In simpler words, we can get the number of times a sequence of bytes occurs within a given ByteArray using this method. ...
