python - Converting an if/else block with True/False statements into a dictionary -

-

i iterating through characters in string, , want determine type of each character.

this can done if/else block:

    if char.isdigit():         char_type = 'number'     elif char.isalpha():         char_type = 'letter'     elif char in {'*', '/', '+', '-', '='}:         char_type = 'operator'     else:         char_type = 'other'

if code this:

    if val == 1:         char_type = 'number'     elif val == 2:         char_type = 'letter'     elif val == 3:         char_type = 'operator'

the dictionary be:

d = {1: 'number', 2: 'letter', 3: 'operator'}

but in case, each of statements either true or false. can converted dictionary?

yes, can use d[char] syntax, hardly sees worth cost in complexity , readability.

you encapsulate if/else in __getitem__ method of class, , use [] syntax retrieve character type, so:

class chartype:     def __getitem__(self, char):         if char.isdigit():             char_type = 'number'         elif char.isalpha():             char_type = 'letter'         elif char in {'*', '/', '+', '-', '='}:             char_type = 'operator'         else:             char_type = 'other'         return char_type  d = chartype()  print(d["a"], d["+"])

c - zlib and gdi32 with OpenSSL? -

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.

when draw attributed string fixed line height text kit, characters aligned bottom of line fragment. while make sense on 1 line characters varying in size, breaks flow of text multiple lines. baselines appear decided largest descender each line. i've found article people behind sketch explaining exact problem in bit more detail , showing solution does, not explaining how achieved this. this want basically: when showing 2 lines large line height, result far ideal: the code i'm using: let smallfont = uifont.systemfont(ofsize: 15) let bigfont = uifont.systemfont(ofsize: 25) let paragraphstyle = nsmutableparagraphstyle() paragraphstyle.minimumlineheight = 22 paragraphstyle.maximumlineheight = 22 var attributes = [ nsfontattributename: smallfont, nsparagraphstyleattributename: paragraphstyle ] let textstorage = nstextstorage() let textcontainer = nstextcontainer(size: cgsize(width: 250, height: 500)) let layoutmanager = nslayoutmanager() textstorage.append(n...
