根据我对您的列表内容的理解,您可以使用如下内容:
businesses = ["C1 count B1", "C2 count B2", "C1 count B3"]
cities = ["C1","C3","C4"]
output = [a for a in businesses if a.split()[0] in cities]
print(output)
假设空格分隔第一个列表中每个项目的组成部分,则会产生:
['C1 count B1', 'C1 count B3']

您错过了内部for循环的缩进
for item1 in A:
for item2 in B:
if item1 == item2:
print(item1)
或者您可以使用setif 两个列表中的值都是单个单词来执行此操作
list(set(A).intersection(set(B)))
从你的问题来看,它是列表中单词的组合
businesses = ["C1 count B1", "C2 count B2", "C1 count B3"]
cities = ["C1","C3","C4"]
for city in cities:
for business in businesses:
if city in business.split():
print(city, business)

for local_city in list_of_cities_in_our_district:
for entry in list_of_city_county_business:
if entry's city matches local_city:
print the business name
这是一些伪代码,应该可以完成您想要的操作...我将语义细节留给您,用于解析列表的布局等。

鉴于所提供的数据文件中的数据格式不完美,以下代码可能会工作得更好。它还有一个额外的优点,即按照城市在 cars.txt 文件中出现的顺序按城市对结果进行分组。
with open('Cities.txt', encoding='utf-8') as f: cities = f.read().split('\n')
cities = [x.strip() for x in cities if x]
with open('Businesses.txt', encoding='utf-8') as f: businesses = f.read().split('\n')
businesses = [x for x in businesses if x]
found = 0
for c in cities:
for b in businesses:
if b.startswith(c):
found += 1
print(b)
print(f'Found {found} businesses')

完整的解决方案,由于非结构化数据需要大量格式化。
with open("Businesses.txt", mode='r') as f:
listBusinesses = f.readlines()
with open("Cities.txt", mode='r') as f:
listCities = f.readlines()
Cities = []
for values in listCities:
if len(values.split('\n')[0]) > 0:
Cities.append(values.split('\n')[0])
CityNames = []
BusinessNames = []
SerialNo = []
for values in listBusinesses:
if len(values.split('\n')[0]) > 0:
vCityNames = values.split('\n')[0][:26].strip()
CityNames.append(vCityNames)
vSerialWithBusiness = values.split('\n')[0][26:].strip()
if len(vSerialWithBusiness.split('\n')[0].split('.')) > 1:
vSerialNo = (vSerialWithBusiness.split('\n')[0].split('.')[0].strip())
SerialNo.append(vSerialNo)
vBusinessNames = (vSerialWithBusiness.split('\n')[0].split('.')[1].strip())
else:
vBusinessNames = (vSerialWithBusiness.split('\n')[0].split('.')[0].strip())
SerialNo.append('Missing')
BusinessNames.append(vBusinessNames)
assert len(CityNames) == len(SerialNo) == len(BusinessNames)
count = 0
for x in range(len(Cities)):
for y in range(len(CityNames)):
if Cities[x] == CityNames[y]:
count = count + 1
print(Cities[x].ljust(27,' ') ,SerialNo[y].ljust(7,' '), BusinessNames[y])
# Total Businesses 3488, matching Cities 345
