Python Strings encode () method

In today`s world, security is key in many applications. Thus, a secure storage of passwords in the database is required and therefore there is a need to store encoded versions of strings. To achieve this, Python has defined “ encode () ” in its language, which encodes strings with the specified encoded schema. There are several coded schemes defined in the language.

Code # 1: Code for printing the available coding schemes.

# Python3 printable code
# all available encodings


from encodings.aliases import aliases

# Print list available

print ( "The available encodings are:" )

print (aliases.keys ( ))


 The available encodi ngs are: dict_keys ([`ibm039`,` iso_ir_226`, `1140`,` iso_ir_110`, `1252`,` iso_8859_8`, `iso_8859_3`,` iso_ir_166`, `cp367`,` uu`, `quotedprintable`, `ibm775`,` iso_8859_16_2001`, `ebcdic_cp_ch`,` gb2312_1980`, `ibm852`,` uhc`, `macgreek`,` 850`, `iso2022jp_2`,` hz_gb_2312`, `elot_88928_p_,` iso `,` iso_ir_199`, `ibm865`,` cspc862latinhebrew`, `863`,` iso_8859_5`, `latin4`,` windows_1253`, `csisolatingreek`,` latin5`, `855`,` windows_1256`, `rot13`, `ms1361`,` windows_1254`, `ibm863`,` iso_8859_14_1998`, `utf8_ucs2`,` 500`, `iso8859`,` 775`, `l7`,` l2`, `gb18030_2000`,` l9`, `utf_32be `,` iso_ir_100`, `iso_8859_4`,` iso_ir_157`, `csibm857`,` shiftjis2004`, `iso2022jp_1`,` iso_8859_2_1987`, `cyrillic`,` ibm861`, `ms950`,` 8664` `csibm863`,` 932`, `iso_8859_14`,` cskoi8r`, `csptcp154`,` 852`, `maclatin2`,` sjis`, `korean`,` 865`, `u32`,` csshiftjis`, `dbcs `,` csibm037`, `csibm1026`,` bz2`, `quopri`,` 860`, `1255`,` 861`, `iso_ir_127`,` iso_celtic`, `chinese`,` l8`, `1 258`, `u_jis`,` cspc850multilingual`, `iso_2022_jp_2`,` greek8`, `csibm861`,` 646`, `unicode_1_1_utf_7`,` ibm862`, `latin2`,` ecma_118`, `csisolatinlib`, csis` csisolatin` , `iso2022jp_3`,` ksx1001`, `858`,` hkscs`, `shiftjisx0213`,` base64`, `ibm857`,` maccentraleurope`, `latin7`,` ruscii`, `cp_is`,` iso_ir_101`, ` us_ascii`, `hebrew`,` ansi_x3.4_1986`, `csiso2022jp`,` iso_8859_15`, `ibm860`,` ebcdic_cp_us`, `x_mac_simp_chinese`,` csibm855`, `1250`,` macoeland` iso2022jp`, `u16`,` u7`, `s_jisx0213`,` iso_8859_6_1987`, `csisolatinhebrew`,` csibm424`, `quoted_printable`,` utf_16le`, `tis260`,` utf`, `_ch_chinese6_trad` , `cp866u`,` jisx0213`, `csiso58gb231280`,` windows_1250`, `cp1361`,` kz_1048`, `asmo_708`,` utf_16be`, `ecma_114`,` eucjis2004`, `x_mac_f8anese`,` utf_ iso_ir_6`, `cp_gr`,` 037`, `big5_tw`,` eucgb2312_cn`, `iso_2022_jp_3`,` euc_cn`, `iso_8859_13`,` iso_8859_5_1988`, `maccyrillic_560` ks1_1988`, `maccyrillic_560` ks1_1988`, `maccyrillic_560` ks1_1988` , `roman8`,` csibm500`, `ujis`,` arab ic`, `strk1048_2002`,` 424`, `iso_8859_11_2001`,` l5`, `iso_646.irv_1991`,` 869`, `ibm855`,` eucjisx0213`, `latin1`,` csibm866`, `ibm864`,` ibm864` big5_hkscs`, `sjis_2004`,` us`, `iso_8859_7`,` macturkish`, `iso_2022_jp_2004`,` 437`, `windows_1255`,` s_jis_2004`, `s_jis`,` 1257`, `ebcj_cp` , `ms949`,` utf32`, `shiftjis`,` latin`, `windows_1251`,` 1125`, `ks_x_1001`,` iso_8859_10_1992`, `mskanji`,` cyrillic_asian`, `ibm273`,` tis620`, ` 1026`, `csiso2022kr`,` cspc775baltic`, `iso_ir_58`,` latin8`, `ibm424`,` iso_ir_126`, `ansi_x3.4_1968`,` windows_1257`, `windows_1252`,` 949`, `base_64`,` ms936`, `csisolatin2`,` utf7`, `iso646_us`,` macroman`, `1253`,` 862`, `iso_8859_1_1987`,` csibm860`, `gb2312_80`,` latin10`, `ksc5601`,` iso_8859_10 , `utf8_ucs4`,` csisolatin4`, `ebcdic_cp_be`,` iso_8859_1`, `hzgb`,` ansi_x3_4_1968`, `ks_c_5601`,` l3`, `cspc8codepage437`,` ib500` iso_8859_7m_19500` ibm1026`, `iso_8859_6`,` csibm865`, `ibm866`,` windows_1258`, `iso_ir_138`,` l 4`, `utf_32le`,` iso_8859_11`, `thai`,` 864`, `euc_jis2004`,` cp936`, `1251`,` zip`, `unicodebigunmarked`,` csHPRoman8`, `csibm858`,` utf16` , `936`,` ibm037`, `iso_8859_8_1988`,` 857`, `csibm869`,` ebcdic_cp_he`, `cp819`,` euccn`, `iso_8859_2`,` ms932`, `iso_2022_jp_201_k csisolatin6`, `iso_2022_jp`,` x_mac_korean`, `latin3`,` csbig5`, `hz_gb`,` csascii`, `u8`,` csisolatin5`, `csisolatincyrillic`,` ms_kanji`2`, `cspcp85k10 , `iso2022jp_ext`,` csibm273`, `iso_2022_jp_ext`,` ibm858`, `ibm850`,` sjisx0213`, `tis_620_2529_1`,` l10`, `iso_ir_109`,` ibm4125, `euck tis_620_0`, `l1`,` ibm819`, `iso2022kr`,` ibm367`, `950`,` r8`, `hex`,` cp154`, `tis_620_2529_0`,` iso_8859_16`, `pt154`,` ebcdic_cp , `ibm1140`,` l6`, `csibm864`,` csisolatin1`, `csisolatin3`,` latin6`, `iso_8859_9_1989`,` iso_8859_3_1988`, `unicodelittleunmarked`,` macintosh`, `273`,` latin9 iso_8859_4_1988`, `iso_8859_9`,` ebcdic_cp_nl`, `iso_ir_144`]) 

Strings can use function encode (), which returns the encoded version of the string according to the specified encoding.

Syntax: encode (encoding, error)

encoding: Specifies the encoding on the basis of which encoding has to be performed.
error: Decides how to handle the errors if they occur, eg `strict` raises Unicode error in case of exception and `ignore` ignores the errors occurred.

Returns: Returns the string in the encoded form

Code # 2: Code to encode the string

# Python code for demonstration
# encode ()

# initialization string

str < / code> = "pythonengineering"

# print the encoded string

print " The encoded string in base64 format is: " ,

print str . encode ( `base64` , `strict` )


 The encoded string in base64 format is: Z2Vla3Nmb3JnZWVrcw ==
