【问题描述】：

# 1. Create a list of all of the names
name = ["kaki", "helen", "makir", "pallu"]

print("My cousins are" + name+ "but helen is different than them.")

错误：

 ----- print("My cousins are" + name+ "but helen is different than them.")
TypeError: can only concatenate str (not "list") to str. -----

【问题讨论】：

你不能把列表类型放到你的字符串中
您的错误与错误消息中报告的完全一样，您的代码正在将 (+) list [...] 添加到 str "My cousins are"，这是不可能的因为它们是不同的类型。
print("My cousins are " + ','.join(name)+ " but helen is different than them.") 或 print("My cousins are " + str(name)[1:-1]+ " but helen is different than them.") 您正在将列表连接到字符串。

【解决方案1】：

试试：

print("My cousins are " + str(name) + " but helen is different than them.")

【解决方案2】：

不要与+连接，只需改为逗号即可：

name = ["kaki", "helen", "makir", "pallu"]

print("My cousins are", name, "but helen is different than them.")

这是输出：

My cousins are ['kaki', 'helen', 'makir', 'pallu'] but helen is different than them.
