`base64.b64encode()`¶

base64.b64encode(s, altchars=None)[source]¶

Encode a string using Base64.

s is the string to encode. Optional altchars must be a string of at least length 2 (additional characters are ignored) which specifies an alternative alphabet for the ‘+’ and ‘/’ characters. This allows an application to e.g. generate url or filesystem safe Base64 strings.
