如何修改输出

Question

def noalpha(s): 

    noa = '' 
    for c in s: 
     if not (c in noa or c.isalpha()): 
      noa += c 
    return noa 

def flines(t, ww): 

    s=noalpha(t) 
    lines=t.lower().splitlines() 
    lst=[] 
    for i in range(len(lines)): 
     for caratteri in s: 
      lines[i]=lines[i].replace(caratteri, ' ') 
     wrdst=lines[i].split() 
     l= 'Line ' +str(i)+': ' 
     False 
     for k in ww: 
      k=k.lower() 
      num=wrdst.count(k) 

      if num>0: 
       l+='"'+ str(k) + '"=' + str(num)+' ' 
       True 
     if True: 
      lst+=[l] 


    return lst 

有人可以向我解释我如何修改输出，使空行不出现？输出运行程序后，我得到的是：

['Line 0: "to"=1 ', 'Line 1: "the"=1 ', 'Line 2: "the"=1 ', 'Line 3: "to"=1 ', 'Line 4: "so"=2 ', 'Line 5: ', 'Line 6: ', 'Line 7: "to"=1 "the"=1 ', 'Line 8: "to"=1 "the"=2 ', 'Line 9: ', 'Line 10: ', 'Line 11: "to"=1 "the"=1 ', 'Line 12: ', 'Line 13: ', 'Line 14: "so"=1 ', 'Line 15: "to"=1 ', 'Line 16: ', 'Line 17: ', 'Line 18: "to"=1 "the"=2 ', 'Line 19: "the"=1 ', 'Line 20: "the"=4 ', 'Line 21: ', 'Line 22: ', 'Line 23: ', 'Line 24: ', 'Line 25: ', 'Line 26: ', 'Line 27: "the"=1 ', 'Line 28: ', 'Line 29: ', 'Line 30: "the"=1 ', 'Line 31: '] 

Answer 1

尽管此代码是不漂亮做您需要的资料，做你需要的，如果将其更改为改变这些线

if num>0: 
    l+='"'+ str(k) + '"=' + str(num)+' ' 
    True 
if True: 
    lst+=[l] 

像

if num>0: 
    l+='"'+ str(k) + '"=' + str(num)+' ' 
    flag = True 
if flag: 
    lst+=[l] 

然后如果您在for循环开始时重新初始化flag = False，它应该产生您想要的结果。通过做如果真如果你是说总是追加到列表vs当实际上有东西
