It is not easy to decode this information in disassemble output. Proposed patch makes disassembler producing human readable representation of FORMAT_VALUE argument.$ echo 'f"{a} {b:4} {c!r} {d!r:4}"' | ./python -m dis 1 0 LOAD_NAME 0 (a) 2 FORMAT_VALUE 0 4 LOAD_CONST 0 (' ') 6 LOAD_NAME 1 (b) 8 LOAD_CONST 1 ('4') 10 FORMAT_VALUE 4 (with format) 12 LOAD_CONST 0 (' ') 14 LOAD_NAME 2 (c) 16 FORMAT_VALUE 2 (repr) 18 LOAD_CONST 0 (' ') 20 LOAD_NAME 3 (d) 22 LOAD_CONST 1 ('4') 24 FORMAT_VALUE 6 (repr, with format) 26 BUILD_STRING 7 28 POP_TOP 30 LOAD_CONST 2 (None) 32 RETURN_VALUE | |||
