在终端或python中打印x个字符？(Printing x amounts of characters in terminal or python?)

在终端或python中打印x个字符？(Printing x amounts of characters in terminal or python?)

如果我需要x个字符来测试我的程序，有没有办法用linux中的终端快速生成它们？ 还是在python中？ 例如，我想测试当我输入80个字符时我的程序是否中断。 但是，我希望能够在终端中生成80个字符，然后将其粘贴到我的程序（或管道等），而不是写80个字符。 我尝试过：

>>> for item in range (1,80): ... print "x",

它可以工作，但它打印x，中间有空格，超过80个字符

If i need x amount of characters to test my program, is there a way of generating them quickly with terminal in linux? or in python? for example I want to test if my program breaks when I enter 80 characters. But instead of writing 80 characters I want to be able to just generate 80 characters in terminal and then copy paste it to my program (or pipeline it etc). I tried doing:

>>> for item in range (1,80): ... print "x",

It works but it prints x with spaces inbetween which would be more than 80 characters

它必须是'x'吗？ 对于随机字符串，您可以在shell中使用它

$ dd if=/dev/urandom count=80 bs=1

Does it have to be 'x's? For a random string you can use this from the shell

$ dd if=/dev/urandom count=80 bs=1
