How to encode text to base64 in python

Question

I am trying to encode a text string to base64   i tried doing this    name    your name  print  encoding  s in base64 yields    s n   name name encode  base64   strict       But this gives me the following error   LookupError   base64  is not a text encoding  use codecs encode   to handle arbitrary codecs   How do I go about doing this     using Python 3 4

Remember to import base64 and that b64encode takes bytes as an argument   import base64 base64 b64encode bytes  your string    utf-8

To compatibility with both py2 and py3  import six import base64  def b64encode source       if six PY3          source   source encode  utf-8       content   base64 b64encode source  decode  utf-8

It turns out that this is important enough to get it s own module     import base64 base64 b64encode b your name      b eW91ciBuYW1l  base64 b64encode  your name  encode  ascii       b eW91ciBuYW1l

Use the below code    import base64   Taking input through the terminal  welcomeInput  raw input  Enter 1 to convert String to Base64  2 to convert Base64 to String       if int welcomeInput   1 or int welcomeInput   2        Code to Convert String to Base 64      if int welcomeInput   1          inputString  raw input  Enter the String to be converted to Base64             base64Value   base64 b64encode inputString encode            print  Base64 Value       base64Value      Code to Convert Base 64 to String      elif int welcomeInput   2          inputString  raw input  Enter the Base64 value to be converted to String             stringValue   base64 b64decode inputString  decode  utf-8           print  Base64 Value       stringValue  else      print  Please enter a valid value

For py3  base64 encode and decode string  import base64  def b64e s       return base64 b64encode s encode    decode     def b64d s       return base64 b64decode s  decode

It looks it s essential to call decode   function to make use of actual string data even after calling base64 b64decode over base64 encoded string  Because never forget it always return bytes literals   import base64 conv bytes   bytes  your string    utf-8   print conv bytes                                    b your string  encoded str   base64 b64encode conv bytes  print encoded str                                   b eW91ciBzdHJpbmc   print base64 b64decode encoded str                  b your string  print base64 b64decode encoded str  decode          your string

Whilst you can of course use the base64 module  you can also to use the codecs module  referred to in your error message   for binary encodings  meaning non-standard  amp  non-text encodings    For example   import codecs my bytes   b Hello World   codecs encode my bytes   base64   codecs encode my bytes   hex   codecs encode my bytes   zip   codecs encode my bytes   bz2     This can come in useful for large data as you can chain them to get compressed and json-serializable values   my large bytes   my bytes   10000 codecs decode      codecs encode          codecs encode              my large bytes               zip                      base64         utf8      Refs    https   docs python org 3 library codecs html binary-transforms https   docs python org 3 library codecs html standard-encodings https   docs python org 3 library codecs html text-encodings

1  This works without imports in Python 2    gt  gt  gt   gt  gt  gt   Some text  encode  base64    U29tZSB0ZXh0 n   gt  gt  gt   gt  gt  gt   U29tZSB0ZXh0 n  decode  base64    Some text   gt  gt  gt   gt  gt  gt   U29tZSB0ZXh0  decode  base64    Some text   gt  gt  gt     although this doesn t work in Python3    2  In Python 3 you d have to import base64 and do base64 b64decode        - will work in Python 2 too
