如何将用户输入的值变成一个可用值的变量？

Question

from turtle import*

branch_width=4
grass_color=input("Would you like your grass to be snowy, dead, or healthy? ")
sky_color=input("Would you like it to be morning, afternoon, or evening? ")

morning="cadetblue"
afternoon="cornflowerblue"
evening="royalblue"
snowy="snow"
dead="wheat"
healthy="darkgreen"

每次我尝试将输入用作 color(sky_color) 时，用户的输入都不会转换为 morning="cadetblue"，等等，这 returns 是一个错误。我该如何解决？我是否只需要让用户输入颜色？

Answer 1

您混淆了变量名和字符串。您将名为 morning 的变量设置为字符串 "cadetblue"。这与输入字符串 "morning" 无关。您必须明确设置。

字典会有所帮助：

interpret_color = {
    "morning": "cadetblue",
    "afternoon": "cornflowerblue",
    "evening": "royalblue",
    "snowy": "snow",
    "dead": "wheat",
    "healthy": "darkgreen"
}

现在你可以试试

color(interpret_color(sky_color))
