Barcelona_venues
是一个包含两列的 Pandas 数据框(列 Neighborhood
具有邻域值,列 Venue Category
具有场地类别值)。两者都包含字符串值。
我想知道 Barcelona_venues
中的每个街区,interesting_venues
列表中包含的场地数量。
我收到以下错误:
<块引用>ValueError:系列的真值不明确。使用 a.empty、a.bool()、a.item()、a.any() 或 a.all()。
interesting_venues = ["Café", "Bar", "Market", "Pharmacy", "Train Station", "Supermarket", "Convenience Store", "Flower Shop", "Cafeteria", "Metro Station"]
lst = []
Neigh = Barcelona_venues["Neighborhood"].unique()
for i in Neigh:
count = ((Barcelona_venues[Barcelona_venues["Venue Category"] in interesting_venues]) and (Barcelona_venues[Barcelona_venues["Neighborhood"] == i]))
lst.append[count]
lst
答案 0 :(得分:0)
你可以试试:
interesting_venues = ["Café", "Bar", "Market", "Pharmacy", "Train Station", "Supermarket", "Convenience Store", "Flower Shop", "Cafeteria", "Metro Station"]
lst = []
Neigh = Barcelona_venues["Neighborhood"].unique()
# Loop through each neighborhood
for i in Neigh:
count = 0
# Loop through all venue categories for each neighborhood
for j in Barcelona_venues[Barcelona_venues["Neighborhood"]==i]["Venue Category"]:
# If it's an interesting category
if j in interesting_venues:
count++
lst.append[count]
