如何根据用户输入的内容打印出一定数量的字母？

Question

像这样的

Underscores = int(input("Enter a number: "))
print("^" + Underscores + "^")

这就是我试图做的，但它不起作用，你可能理解我试图从代码。基本上，用户在一个“^^”表情符号中输入他们想要多少个“”，例如如果输入是4，它将打印出“^\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。如果输入是10，它会打印出“^\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

到目前为止，我只尝试过这个代码，并在网上查看了其他源代码

你很接近。可以在python中对字符串进行乘法，以便：

'_' * 4

给你：

'____'

因此，您只需对代码稍作更改：

n = int(input("Enter a number: "))
print("^" + '_' * n  + "^")

# or maybe cleaner:
print("^{}^".format("_" * n))
