Scanning a file character by character
Hi. Does anyone know how to scan a file character by character and have each character so I can put it into a variable. I am attempting to make a chatbot and need this to read the saved input to look for spelling mistakes and further analysis of user input. Thanks Spacebar265 -- http://mail.python.org/mailman/listinfo/python-list

How else would you check for spelling mistakes? Because input would be very unlikely to be lengthy paragraphs I wouldn't even need very many variables. If anyone could suggest an alternative method this would be much appreciated. -- http://mail.python.org/mailman/listinfo/python-list

How would I do separate lines into words without scanning one character at a time? -- http://mail.python.org/mailman/listinfo/python-list

Using this code how would it load each word into a temporary variable.
