? ? 進(jìn)入編寫阿里云在線的OCR程序，也順便提前了json字符串和python字典的轉(zhuǎn)換及使用，由于涉及到字典的變量問(wèn)題，順便寫了一個(gè)迭代dict字典類的函數(shù)，供大家參考學(xué)習(xí)。
# dict字典迭代函數(shù)
def dictIterator(value, key:str ='', i:int = -1):# value為字典的value，key為字典的key，i為字典所在層級(jí)數(shù)
? ? i +=1
? ? if type(value) ==dict:# 判斷輸入類型是為字典類型
? ? ? ? for (k, v)in value.items():# 如果是字典類型則遍歷字典原始
? ? ? ? ? ? dictIterator(v, k, i)# 并回調(diào)迭代函數(shù)自身
? ? elif type(value) ==list:# 如果類型為list，則為字典對(duì)象數(shù)組，則做數(shù)組遍歷出字典對(duì)象
? ? ? ? for datain value:
for (data_k, data_v)in data.items():# 遍歷數(shù)組中單個(gè)字典對(duì)象，并回調(diào)迭代函數(shù)自身
? ? ? ? ? ? ? ? dictIterator(data_v, data_k, i)
else:# 如果既不是字典對(duì)象，也不是數(shù)組對(duì)象，則直接輸出
? ? ? ? tabStr =''
? ? ? ? for bin range(i):
tabStr +='? ? '? # 在打印過(guò)程中體現(xiàn)不同層級(jí)縮進(jìn)
? ? ? ? print('Level[', i, "]:", tabStr, key, ":", value)
