pretty print - Python printing text: Highlight or mark some text in the string with indicators -


i want print string buffer (or byte array) contains special characters, such \t , \n, besides that, need print indicators below line indicate special part of string, below:

a b c d \t , e f g \n    ~~~~~~~~   ^^^^^

here questions:

1, escape char , normal char should printed in fixed width, see repr() function can not.

2, indicator below first line should printed.

3, if still use repr() function, think marker in second line should calculated dynamically, because repr() don't print texts in fixed width format, \t takes 2 chars.

any 1 can help?

btw: whole idea want create python pretty printer gdb show token when debugging parsing algorithm.

edit: here example:

print (repr("abcd\t,efg\n"))

when run code, printed string has 12 element instread of 10, me, ff want hight token "efg", index 6,7,8 in string, if draw markers in second index 6,7,8, following.

abcd\t,efg\n       ~~~

because "\t" has 2 chars not one, means function repr() don't print fixed witdh chars, in case, see:

abcd\t,efg\n        ~~~

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
