Given a String, convert its characters to unicode characters.
Input : test_str = ‘gfg’
Output : \u0067\u0066\u0067
Explanation : Result changed to unicoded string.
Input : test_str = ‘himani’
Output : \u0068\u0069\u006D\u0061\u006E\u0069
Explanation : Result changed to unicoded string.
Method #1 : Using re.sub() + ord() + lambda
In this, we perform the task of substitution using re.sub() and lambda function is used to perform the task of conversion of each characters using ord().
Python3
# Python3 code to demonstrate working of# Convert String to unicode characters# using re.sub() + ord() + lambdaimport re# initializing stringtest_str = 'neveropen'# printing original Stringprint("The original string is : " + str(test_str))# using sub() to perform substitutions# ord() for conversion.res = (re.sub('.', lambda x: r'\u % 04X' % ord(x.group()), test_str))# printing resultprint("The unicode converted String : " + str(res)) |
Output
The original string is : neveropen The unicode converted String : \u0067\u0065\u0065\u006B\u0073\u0066\u006F\u0072\u0067\u0065\u0065\u006B\u0073
Time Complexity: O(n)
Auxiliary Space: O(n)
Method #2 : Using join() + format() + ord()
In this, task of substitution in unicode formatted string is done using format() and ord() is used for conversion.
Python3
# Python3 code to demonstrate working of# Convert String to unicode characters# using join() + format() + ord()import re# initializing stringtest_str = 'neveropen'# printing original Stringprint("The original string is : " + str(test_str))# using format to perform required formattingres = ''.join(r'\u{:04X}'.format(ord(chr)) for chr in test_str)# printing resultprint("The unicode converted String : " + str(res)) |
Output
The original string is : neveropen The unicode converted String : \u0067\u0065\u0065\u006B\u0073\u0066\u006F\u0072\u0067\u0065\u0065\u006B\u0073
Time Complexity: O(n)
Auxiliary Space: O(n)
