如何在Python中将迭代值分配给多个全局变量

Question

我正在查询具有某些特定列的表，并希望将每个值存储在不同的全局变量中。

当我只尝试查询一行时，我可以将值存储在全局变量中，但是当我将LIMIT增加超过一个时，我的代码将不起作用。

query = Select event, date, city, country from Table LIMIT 1;

event = ""
date = ""
city = ""
country = ""  

for row in cur.execute(query):
global event
global date
global city
global country

event, date, city, country = [row[i] for i in (0, 1, 2, 3)]

我想在每次迭代中将新值存储在全局变量中。结果应如下所示：-

Output: (On 1st Iteration)
event ="ABC"
date ="12 June"
city ="Delhi"
country ="India"

Output: (On 2nd Iteration)
event ="XYZ"
date ="2 May"
city ="New York"
country ="USA"

Output: (On 3rd Iteration)
event ="DDD"
date ="15 Sep"
city ="Tokyo"
country ="Japan"
