我正在尝试完成一项初学者作业,该作业需要引用列表中元组中的元素,该列表使用 for 循环和条件来根据元组中的值输出两种类型的字符串之一。
Using a for loop and an if statement, go through vacc_counties and print out a message for those counties that have a higher than 30% vaccination rate.
Add another loop that prints out a message for every county, but prints different messages if the rate is above or below 30.
Example:
Benton County is doing ok, with a rate of 41.4%
Fulton County is doing less ok, with a rate of 22.1%
这是元组列表,后跟我自己的代码:
vacc_counties = [('Pulaski', 42.7), ('Benton', 41.4), ('Fulton', 22.1), ('Miller', 9.6),
('Mississippi', 29.4), ('Scotty County', 28.1)]
for tuple in vacc_counties:
for element in tuple:
if [1] < 30:
print(f"{vacc_counties[0]}is doing ok, with a rate of" [1]"%")
else [1] n > 30:
print(f"{vacc_counties[0]}is doing ok, with a rate of" [1]"%")
最佳答案
备注:
- 不要对变量名使用保留字,例如使用
tpl
而不是tuple
- 删除元组中的
for元素:
循环 - 要访问元组的第二个元素,请使用
tpl[1]
而不是[1]
- 使用
elif
代替else
更正的代码:
vacc_counties = [
("Pulaski", 42.7),
("Benton", 41.4),
("Fulton", 22.1),
("Miller", 9.6),
("Mississippi", 29.4),
("Scotty County", 28.1),
]
for tpl in vacc_counties:
if tpl[1] < 30:
print(f"{tpl[0]} is doing less ok, with a rate of {tpl[1]}%")
elif tpl[1] >= 30:
print(f"{tpl[0]} is doing ok, with a rate of {tpl[1]}%")
打印:
Pulaski is doing ok, with a rate of 42.7%
Benton is doing ok, with a rate of 41.4%
Fulton is doing less ok, with a rate of 22.1%
Miller is doing less ok, with a rate of 9.6%
Mississippi is doing less ok, with a rate of 29.4%
Scotty County is doing less ok, with a rate of 28.1%
