遍歷字典列表

Question

遍歷字典列表並打印出每個高中及其類型

高中字典和學校類型。

high_school_types = [{"High School": "Griffin", "Type":"District"},
                    {"High School": "Figueroa", "Type": "District"},
                    {"High School": "Wilson", "Type": "Charter"},
                    {"High School": "Wright", "Type": "Charter"}]

for index in range(len(high_school_types)):
    for key, value in high_school_types.items():
        print(key, value)

導致錯誤：'list' 對象沒有屬性 'items'

Answer 1

TL; 博士

你在第 7 行打了一個錯字，應該是

for key, value in high_school_types[index].items():

完整代碼

high_school_types = [{"High School": "Griffin", "Type":"District"},
                    {"High School": "Figueroa", "Type": "District"},
                    {"High School": "Wilson", "Type": "Charter"},
                    {"High School": "Wright", "Type": "Charter"}]

for index in range(len(high_school_types)):
    for key, value in high_school_types[index].items():
        print(key,value)

長版

lists沒有.items()方法，但字典有。 當調用high_school_types的錯誤items()方法（不存在）時，Python 會拋出錯誤，因為它不存在。

相反，您需要使用循環變量 index 對high_school_types進行index 。 這個索引值將是一個字典，並將具有.items()方法。
