DESCRIPTION¶
Return 0 or 1 if bit n was set in string str.
Each character contains 6 bits. So you can store a value between 0 and 63 in one character (2^6=64). Starting character is the blank char: (U+00020 SPACE) which has the value 0. The first character in the string is the one with the lowest bits (0-5).
USAGE¶
The below returns 1 because “_” stands for the number 63 and therefore the 6th bit is set:
test_bit("_",5);
The next example returns 0 because char: (U+00020 SPACE) stands for 0 and no bit is set:
test_bit(" ",3);
