Python如何实现用户信息录入后按指定格式回显输出

代码无法正常运行主要是两个问题：

• 你定义的info字典键名不统一，部分键末尾带冒号（比如"Name:"）、部分不带（比如"Desired Course"），取值时只要键名写的和定义时不完全一致，就会触发KeyError报错。
• 你写的输出模板本身存在语序错误，you were born in "Birthdate" years old逻辑不通，出生日期字段后多余的years old是写模板时串了后面的年龄字段导致的。

可直接运行的代码 #

先统一字典键名，去掉所有键末尾多余的冒号降低出错概率，再用f-string做字符串格式化即可：

# 统一键名后的信息存储结构
info = {
    "Name": "x",
    "Birthdate": "x",
    "Gender": "x",
    "Age": "x",
    "Nationality": "x",
    "Desired Course": "x",
    "Motto in life": "x",
    "Dreams in life": "x",
    "Favorite hobby": "x"
}

# 收集用户输入（替换成你原有的输入逻辑即可）
info["Name"] = input("Enter your name: ")
info["Birthdate"] = input("Enter your birthdate: ")
info["Gender"] = input("Enter your gender: ")
info["Age"] = input("Enter your age: ")
info["Nationality"] = input("Enter your nationality: ")
info["Desired Course"] = input("Enter your desired course: ")
info["Motto in life"] = input("Enter your motto in life: ")
info["Dreams in life"] = input("Enter your dreams in life: ")
info["Favorite hobby"] = input("Enter your favorite hobby: ")

# 按指定格式回显，已修正模板语序错误
print(f'So your name is "{info["Name"]}" and you were born in "{info["Birthdate"]}" and you\'re a "{info["Age"]}" year old "{info["Nationality"]}" "{info["Gender"]}" that wants to be a "{info["Desired Course"]}" one day and your motto in life is "{info["Motto in life"]}" and "{info["Dreams in life"]}" and your favorite hobby is "{info["Favorite hobby"]}"')

补充说明 #

• 如果你不想修改原有带冒号的字典键，取值时必须严格匹配键名，比如取姓名必须写info["Name:"]，漏写末尾冒号就会报错。
• 字符串内需要输出双引号时，要么外层用单引号包裹整个字符串，要么用转义符\"处理，否则会触发语法错误。
• 如果需要保留你最初写的带冗余years old的语序，直接修改f-string内的对应文本即可，字段取值逻辑不需要改动。
