Python Strings encode() method
In today’s world, security holds the key in many applications. Thus the need for secure storage of passwords in the database is required and hence there is to save encoded versions of strings. To achieve this, python in its language has defined “encode()” that encodes strings with the specified encoding scheme. There are several encoding schemes defined in the language. The Python String encode() method encodes the string, using the specified encoding. If no encoding is specified, UTF-8 will be used.

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, e.g ‘strict’ raises Unicode error in case of exception and ‘ignore’ ignores the errors that occurred. There are six types of error response
- strict – default response which raises a UnicodeDecodeError exception on failure
- ignore – ignores the unencodable unicode from the result
- replace – replaces the unencodable unicode to a question mark ?
- xmlcharrefreplace – inserts XML character reference instead of unencodable unicode
- backslashreplace – inserts a \uNNNN escape sequence instead of unencodable unicode
- namereplace – inserts a \N{…} escape sequence instead of unencodable unicode
Returns:
Returns the string in the encoded form
Example 1: Code to print encoding schemes available
Python3
# Python3 code to print# all encodings availablefrom encodings.aliases import aliases# Printing list availableprint("The available encodings are : ")print(aliases.keys()) |
Output:
The available encodings 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_928', 'iso8859_1', 'eucjp', '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', 'ibm437', '866', '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', '1258', 'u_jis', 'cspc850multilingual', 'iso_2022_jp_2', 'greek8', 'csibm861', '646', 'unicode_1_1_utf_7', 'ibm862', 'latin2', 'ecma_118', 'csisolatinarabic', 'zlib', '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', 'maciceland', 'iso_ir_148', 'iso2022jp', 'u16', 'u7', 's_jisx0213', 'iso_8859_6_1987', 'csisolatinhebrew', 'csibm424', 'quoted_printable', 'utf_16le', 'tis260', 'utf', 'x_mac_trad_chinese', '1256', 'cp866u', 'jisx0213', 'csiso58gb231280', 'windows_1250', 'cp1361', 'kz_1048', 'asmo_708', 'utf_16be', 'ecma_114', 'eucjis2004', 'x_mac_japanese', 'utf8', 'iso_ir_6', 'cp_gr', '037', 'big5_tw', 'eucgb2312_cn', 'iso_2022_jp_3', 'euc_cn', 'iso_8859_13', 'iso_8859_5_1988', 'maccyrillic', 'ks_c_5601_1987', 'greek', 'ibm869', 'roman8', 'csibm500', 'ujis', 'arabic', 'strk1048_2002', '424', 'iso_8859_11_2001', 'l5', 'iso_646.irv_1991', '869', 'ibm855', 'eucjisx0213', 'latin1', 'csibm866', 'ibm864', 'big5_hkscs', 'sjis_2004', 'us', 'iso_8859_7', 'macturkish', 'iso_2022_jp_2004', '437', 'windows_1255', 's_jis_2004', 's_jis', '1257', 'ebcdic_cp_wt', 'iso2022jp_2004', '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', 'iso_8859_7_1987', '8859', 'ibm500', 'ibm1026', 'iso_8859_6', 'csibm865', 'ibm866', 'windows_1258', 'iso_ir_138', 'l4', '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_1', 'iso_2022_kr', 'csisolatin6', 'iso_2022_jp', 'x_mac_korean', 'latin3', 'csbig5', 'hz_gb', 'csascii', 'u8', 'csisolatin5', 'csisolatincyrillic', 'ms_kanji', 'cspcp852', 'rk1048', 'iso2022jp_ext', 'csibm273', 'iso_2022_jp_ext', 'ibm858', 'ibm850', 'sjisx0213', 'tis_620_2529_1', 'l10', 'iso_ir_109', 'ibm1125', '1254', 'euckr', 'tis_620_0', 'l1', 'ibm819', 'iso2022kr', 'ibm367', '950', 'r8', 'hex', 'cp154', 'tis_620_2529_0', 'iso_8859_16', 'pt154', 'ebcdic_cp_ca', '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'])
Example 2: Code to encode the string
Python3
# Python code to demonstrate# encode() # initializing stringstr = "geeksforgeeks" # printing the encoded stringprint ("The encoded string in utf8 format is : ",)print (str.encode('utf8', 'ignore')) |
Output:
The encoded string in utf8 format is : b'geeksforgeeks'
Example 3: Encoding with the error parameter
Python3
# unicode stringstring = 'GeeksforGeeks'# print stringprint('The string is:', string)# ignore errorprint(string.encode("ascii", "ignore"))# replace errorprint(string.encode("ascii", "replace")) |
Output:
The string is: GeeksforGeeks b'GeeksforGeeks' b'GeeksforGeeks'
