在Python 3中使用“”和转义序列？

Question

I am learning Python right now and wanted to try all the escape sequences but my code seems to have a bug. Please help me find it?

My Code:

string = """backslash - \\\nsingle quote - \'\ndouble quote - \"
ASCII bell - \a Lorem
ASCII backspace - \b Lorem
ACII formfeed - \f Lorem
Unicode - \N{prabhu} Ipsum
Carriage return - \r Ipsum
16 bit Hex value - \u1234
32 bit Hex value - \U12345678 ASCII Vertical tab - \v
Octal value character - \123
Hex value - \x12 
"""

print(string)

--> Error: SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 137-146: unknown unicode character name

Answer 1

The culprits are \\N{prabhu} and \\U12345678 .

\\U12345678 is illegal because it is far behind the valid range limit ( 0010ffff ). 12345678 in hex is 305419896 where unicode ends at 1114111 ( 0010ffff ).

\\N{prabhu} is illegal because it is not a valid unicode char name.
