如何將Complex Collection轉換為String？

Question

嘗試創建一個非常基本的腳本，它將顯示一組字符串中的隨機字符串。 但是，我需要它顯示，就好像它是一個打印功能（即沒有括號或逗號）。 我嘗試使用連接並遇到錯誤（不可用類型：列表）

name = ("Tom")
greeting = {
["Hello", name, "How are you today?"],
["Welcome", name, "How was your day?"],
["Greetings", name, "Shall we play a game?"],
["Well hey there", name, "Whats up?"],
}
print (', '.join(greeting))

真的非常感謝任何幫助。

你的問題是你在greeting dictionary ，而不是list 。

繼承了我對您的代碼的修復：

#allows us to use randint function
from random import randint

name = ("Tom")

#change greeting from a dictionary to a list by replacing { with [
greeting = [
["Hello", name, "How are you today?"],
["Welcome", name, "How was your day?"],
["Greetings", name, "Shall we play a game?"],
["Well hey there", name, "Whats up?"],
]
#assign myGreeting as a random num between 0 and 3
myGreeting = randint(0,len(greeting)-1)

#define out output to be printed to console (its a String)
output = ""

#itterate through our random greeting word by word and
#concatinate to output variable one word at a time
for myWord in greeting[myGreeting]:
        output+=myWord+" "

print (output)

輸出：
