我有這段代碼，在這里我要計(jì)算的數(shù)量：.py腳本中的代碼行for_loops（“ for”）-while_loops（“ while”）if_statements（“ if”）函數(shù)定義（“ def”）乘法符號(hào)（“ *”劃分標(biāo)志（“ /”加號(hào)（“ +”）減號(hào)（“-”）在數(shù)學(xué)符號(hào)上，代碼有效，但是當(dāng)代碼正在尋找if語句返回2時(shí)，則存在一個(gè)，這是主要問題，但是這讓我覺得我寫錯(cuò)了for循環(huán)，這可能會(huì)帶來更多錯(cuò)誤以后出現(xiàn)問題。除此之外，我不確定如何打印顯示為[]而不是Author name的Author行代碼：from collections import CounterFOR_=0WHILE_=0IF_=0DEF_=0x =input("Enter file or directory: ")print ("Enter file or directory: {0}".format(x))print ("Filename {0:>20}".format(x))b= open(x)c=b.readlines()d=b.readlines(2)print ("Author {0:<18}".format(d))print ("lines_of_code {0:>8}".format((len (c))))counter = Counter(str(c))for line in c:    if  ("for ") in line:        FOR_+=1        print ("for_loops {0:>12}".format((FOR_)))for line in c:    if  ("while ") in line:        WHILE_+=1        print ("while_loops {0:>10}".format((WHILE_)))for line in c:    if  ("if ") in line:        IF_+=1        a=IF_        print ("if_statements {0:>8}".format((a)))for line in c:    if  ("def ") in line:        DEF_+=1        print ("function_definitions {0}".format((DEF_)))print ("multiplications {0:>6}".format((counter['*'])))print ("divisions {0:>12}".format((counter['/'])))print ("additions {0:>12}".format((counter['+'])))print ("subtractions {0:>9}".format((counter['-'])))正在從以下文件讀取文件：'''DumboAuthor: Hector McTavish'''    for for for  # Should count as 1 for statementwhile_im_alive # Shouldn't count as a whilewhile blah # But this one should  if defined # Should be an if but not a def  def if # Should be a def but not an if    x = (2 * 3) + 4 * 2 * 7 / 1 - 2  # Various operators任何幫助將非常感激
