How do I encode in base64?

How Does Base64 Encoding Work?

Take the ASCII value of each character in the string.
Calculate the 8-bit binary equivalent of the ASCII values.
Convert the 8-bit chunks into chunks of 6 bits by simply re-grouping the digits.
Convert the 6-bit binary groups to their respective decimal values.

How do I get rid of B Python?

Decode() function is used to remove the prefix b of a string. The function is used to convert from the encoding scheme, in which the argument string is encoded to the desired encoding scheme, through which the b prefix gets removed.

How do you decode a string in Python?

decode() is a method specified in Strings in Python 2. This method is used to convert from one encoding scheme, in which argument string is encoded to the desired encoding scheme. This works opposite to the encode. It accepts the encoding of the encoding string to decode it and returns the original string.

How do I encode an image in Python?
