How to use different split delimited string
How to use different segmentation delimiter string, a string based on the resolution delimiter, the character comprising a plurality of different delimiter character as
s = '12 ;; 7.osjd; .jshdjdknx + 'wherein;. + is the separator
What are the solutions?
Method 1: str.split () method, a delimiter per treatment
# / Usr / bin / to python3! DEF go_split (S, Symbol): Result = [S] for I in Symbol: Median = [] # conventional method # for X in Result: # median.extend (x.split (I) # list parsing # [median.extend (y.split (I)) for Y in Y IF Result] # Map higher-order functions, map generation iterables for Z in Map ( the lambda X: x.split (I), Result ): median.extend (Z) # above three methods can solve the problem Result = Median # Remove empty string return [X for X in Result IF X] IF the __name__ == " __main__ " : # define the initial string S = ' 12 is ;; 7.osjd; .jshdjdknx + ' # define separator Symbol = ' ;. / + ' Result = go_split (S, Symbol) Print (Result)
Method 2: re.split () method, a one-time resolved all strings, recommended
# ! / Usr / bin / to python3 Import Re DEF go_split (S, Symbol): # spliced regex Symbol = " [ " + Symbol + " ] + " # split disposable string Result = re.split (Symbol, S ) # remove null character return [X for X in Result IF X] IF the __name__ == " __main__ " : # define the initial string S = ' 12 is ;; 7.osjd; .jshdjdknx + ' # define separator symbol = ';./+' result = go_split(s, symbol) print(result)
A small text-to-speech program, the text after the split, saying a word read out:
# - * - Coding: UTF-. 8 - * - Import pyttsx3 Import Re Import OS Engine = pyttsx3.init () # split description DEF go_split (S, Symbol): # spliced regex Symbol = " [ " + + Symbol " ] + " # disposable string divided Result = re.split (Symbol, S) # remove null character return [X for X in Result IF X] # Analyzing string contains only the Chinese: DEF reflag (List): forI in Range (len (List)): for CH in List [I]: IF CH> = ' \ u4e00 ' and CH <= ' \ u9fa5 ' : return I DEF Reader (List, In Flag): IF In Flag == None : Print ( " This article does Chinese translation " ) the else : Print ( " This article has Chinese translation " ) lenght = len (List) i = 0 the while I < lenght: InStr = INPUT ( " input operation: " + " \ n- " " . 1: Reading continue to listen to the phrase " + " \ n- " " 2: continue to listen to the read word " + " \ n- " + " : " ) IF InStr == " . 1 " : engine.say (List [I]) Print (List [I]) engine.runAndWait () IF InStr == " 2 " : i = i + 1 print(list[i]) engine.say(list[i]) engine.runAndWait() print(list) def start(): dirlsit= os.listdir('reader') for i in range(len(dirlsit)): print(str(i)+":"+str(dirlsit[i])) choice = int(input("输入选择的文章序号：")) with open("reader/"+dirlsit[choice],'r',encoding='utf-8') as f: article = f.read() article = article.replace('\n', '') # 定义分隔符 symbol = ',;.:' list = go_split(article,symbol) if filsh(list): flag = reflag(list) - 1 else:flag=None rate = engine.getProperty('rate') engine.setProperty('rate', rate-25) reader(list,flag) start()

Night after night, she came to tuck me in, even long after my childhood years. Following her longstanding custom, she'd lean down and push my long hair out of the way, then kiss my forehead. I don't remember when it first started annoying me — her hands pushing my hair that way. But it did annoy me, for they felt work-worn and rough against my young skin.
