How to get the ASCII value of a character - Stack Overflow Depending on the number of characters, it could be orders of magnitude faster than calling ord in a loop To use it, wrap a string character in a numpy array and view it as int, which returns the corresponding numeric value (s) of the character (s) in whatever encoding it is in
What does the name of the ord () function stand for? The official Python documentation explains ord(c) ord (c): Given a string representing one Unicode character, return an integer representing the Unicode code point of that character For example, ord ('a') returns the integer 97 and ord ('€') (Euro sign) returns 8364 This is the inverse of chr () It does not specify the meaning of ord, google searches are not helpful What's the origin of it?
python - What does ord (c) and chr (n) do and what does this code . . . Look up what ord (gets a asciis integer value) and chr (turns integer values back into charcters) do As it sits the code is just grabbing the next ascii character (a becomes b) Btw in the future you should read the official documentation before asking a question you could have easily answered yourself
using ord function (ord (B [0]) - ord (0)) - Stack Overflow 0 ord(ch) returns the byte value for a character - "a" is 65, "b" is 66, etc If the character is a digit, ord(ch) - order("0") returns the numeric value of the digit - "0" becomes o, "1" becomes 1, etc The code, overall, parses a strong containing a binary number and collects the value of the number in I
python - Usage of ord (q) and 0xFF - Stack Overflow ord('q') returns the Unicode code point of q cv2 waitkey(1) returns a 32-bit integer corresponding to the pressed key 0xFF is a bit mask which sets the left 24 bits to zero, because ord() returns a value betwen 0 and 255, since your keyboard only has a limited character set Therefore, once the mask is applied, it is then possible to check if it is the corresponding key
