general
1

tell me the function of the “ord”.
Also what does this means,“s,t=input(),[0]*26”.

‘ord’ simply gives you the ascii value of character.

as @sshhhh already told its returns you ascii value.

ord(ASCII char) => integer value of that char(0 - 255)

chr(int val) => will return ascii value at that position.
