遇到的問題及總結(jié):

def fun(a,b,*c,**d): #*args表示位置參數(shù),可以是任何多個(gè)無名參數(shù),*args 會(huì)將參數(shù)打包成tuple給函數(shù)體調(diào)用;**kwargs表示關(guān)鍵字參數(shù),它將參數(shù)打包成dict給函數(shù)調(diào)用。
print(a);
print(b);
print(c);
print(d);
def function(**kwargs):
print( kwargs, type(kwargs))
if __name__ == '__main__':
fun(2,3,'haha','hehe','hoho',x=1,y=2) # 輸出2
# 輸出3
# 輸出('haha', 'hehe', 'hoho') 位置參數(shù),是元組
#輸出 {'y': 2, 'x': 1} 關(guān)鍵字參數(shù),是字典
function(a=2) #輸出 {'a':2} <class 'dict'>
總結(jié)如下:
function(name='xx',color='yy')
可以用 字典打包參數(shù)傳給函數(shù),傳參類型是(兩個(gè)星號)kwargs
dicname={'name':'xx','color'='yy'}
function(**dicname) 和 function(name='xx',color='yy')作用相同數(shù)據(jù)庫查出來的數(shù)據(jù)類型是元組,利用角標(biāo)獲取到元素和sql字符串拼接時(shí)可以不用轉(zhuǎn)格式,%后面直接跟元素
sql語句傳參引用元素時(shí)注意變量值要加雙引號,注意雙引號要轉(zhuǎn)義
在循環(huán)里不要同名變量拼接/引用后再次賦值,如下圖user_find_sql 再次循環(huán)會(huì)產(chǎn)生格式問題,懷疑是把上個(gè)循環(huán)內(nèi)容累加了,修改了變量名解決了
