錯誤與真假

Question

今天我試圖使用布爾表達式（True或False）來完成我的代碼;注意我把這個命令放在if processor['dictionary'] = True。當代碼在那裏時它不能運行。但如果它不在那裏，它可以正常運行。我無法找到阻止我運行此代碼，錯誤作爲錯誤的原因：

IndentationError: expected an indented block

希望你們能幫助我。

dictionary = { 
    "chicken":"chicken two leg animal", 
    "fish":"fish is animal that live under water", 
    "cow":"cow is big vegetarian animal", 
    "space monkey":"monkey live in space", 
} 

print("how can i help you?") 
user_input = raw_input() 
print 
print("You asked: {}.".format(user_input)) 

processor = { 
    "dictionary":False, 
    "dictionary_lookup":[], 
} 

split = user_input.split(" ") 
combos = [' '.join(split[x:y]) for x in range(len(split)) for y in range(len(split)+1) if ' '.join(split[x:y]) != ""] 

for w in split: 

    w = w.lower() 

    if w in dictionary: 
     processor["dictionary"] = True 
     print w 

print combos 

# if processor ["dictionary"] = True 
response = {} 

for item in combos: 
    if dictionary.get(item): 
     response[item] = "what you were looking for is: {}.".format(dictionary[item]) 


if not response: 
    print("Response: I will get back to you!") 
    print 


for ind, (k,v) in enumerate(response.iteritems()): 
    print("Response {}: {} ({})".format(ind+1, v, k)) 
    print

Python的布爾是真/假（用大寫字母）。真不等於真。

檢查對象的truthness可以簡單地

if processor['kamus']: 
    # your code here 

來完成這個工作過程是一樣的你的代碼，它只是更清晰。如果你沒有在你的if語句中加入比較或其他指令，Python會檢查真實性（真或假，有數據或爲空）

錯誤你得到的是因爲你的縮進錯了，你需要有4個空格陳述後（def，if等）
