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 ( ))

Output:

 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)

Parameters:
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’ )

Output:

 The encoded string in base64 format is: Z2Vla3Nmb3JnZWVrcw ==
