[英]Checking if all elements of a List of Lists are in another List of Lists Python
[英]Checking if 3 separate User inputs all match the values of a list of lists in Python
我正在尝试创建一个非常简单的房地产数据库,该数据库将根据用户条件返回属性。
我有以下代码:
import sys
def main():
print ("What type of property are you looking for?")
Type = input()
print ("How big of a property are you looking for?")
Size = input()
print ("Are you looking to lease or purchase a property?")
Listing_Type = input()
a = ('Retail', 1500, 'Lease')
b = ('Industrial', 1440, 'Sale')
c = ('Office', 1000, 'Lease')
Database = (a, b, c)
for i in Database:
if Type == Database[i[0]] and Size == Database[i[1]] and Listing_Type == Database[i[2]]:
text = "There is a %c square foot %d space for %z" % (Database[i[1]], Database[i[0]], Database[i[2]])
else:
i += 1
if matches == 0:
print ("Sorry, there were no matching properties.")
if __name__ == '__main__':
main()
运行此命令时,我收到错误TypeError:元组索引必须是整数或切片,而不是str。
我仍在尝试了解其工作原理。 我需要检查属性类型和列表类型的字符串是否匹配,还要检查大小是否正确。
删除Database[]
in Database[i[0]]
, in Database[i[1]]
, in Database[i[2]]
,您已经在Database
上进行了迭代,因此循环中的i
将是a
, b
,然后c
。 要访问这些元组的值, i[0]
就足够了。
我首先在数据库中
i =('Retail', 1500, 'Lease')
i[0]='Retail'
所以
database[i[0]]=database['Retail']
但是数据库是元组而不是字典
换线
for i in database:
至
for i in range(len(database)):
