Question

我曾经把学生当作字典。但是，当我尝试将输入字符串与字典值（也是一个字符串）匹配时，它会显示

TypeError: string indices must be integers

此代码有什么问题？

students = {
    "Male":["Jones",162,21],
    "Female":["Sarah",162,18]
    }
print(type(students))
for students in students.keys():
    gen = input("What's your gender?: ").strip().capitalize()
    if gen in students:
        name =input("What's your name?: ").strip().capitalize()
        if name == students[gen][0]:
            print("Your name is {}").format(name)

Answer 1

您代码中的

2 错字。试试这个：

students = {
    "Male":["Jones",162,21],
    "Female":["Sarah",162,18]
    }
print(type(students))
for index in students.keys():
    gen = input("What's your gender?: ").strip().capitalize()
    if gen in students.keys():
        name =input("What's your name?: ").strip().capitalize()
        if name == students[gen][0]:
            print("Your name is {}".format(name))

Answer 2

这就是您的代码的样子：

for student in students.keys():
    gen = input("What's your gender?: ").strip().capitalize()
    if gen in students.keys():
        name =input("What's your name?: ").strip().capitalize()
        if name == students[gen][0]:
            print("Your name is {}").format(name)

您的问题是您将变量和字典命名为相同的

。

此版本对我有用：

students = {
"Male": ["Jones", 162, 21],
"Female": ["Sarah", 162, 18]
}
for student in students.keys():
    gen = input("What's your gender?: ").strip().capitalize()
    if gen in student:
        name = input("What's your name?: ").strip().capitalize()
        if name == students[gen][0]:
            print(f"Your name is {name}")
