为什么此代码不打印相同的数字?:
long long a, b;
a = 2147483647 + 1;
b = 2147483648;
printf("%lld\n", a);
printf("%lld\n", b);

我知道 int 变量的最大数量是 2147483647,因为 int 变量是 4 字节。但据我所知,long long 变量是 8 字节,但为什么这段代码会这样呢?
我通过以下命令安装了弹性搜索策展人.
sudo pip install -U elasticsearch-curator

这一切都安装好了.
但是现在当我做以下事情时
curator_cli --version
Run Code Online (Sandbox Code Playgroud)
我得到以下依赖警告.
/usr/local/lib/python2.7/dist-packages/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.

我正在学习 R,并且我在 seq() 上遇到问题\n我知道 seq(0, 3) 是 0 1 2 3。\n但我不知道为什么 seq(0:3) 是1 2 3 4。
\n在 RDocumentation(https://www.rdocumentation.org/packages/base/versions/3.6.2/topics/seq)中,它说
\nseq(from, to)\nseq(from, to, by= )\nseq(from, to, length.out= )\nseq(along.with= )\nseq(from)\nseq(length.out= )\nRun Code Online (Sandbox Code Playgroud)\n第一种形式生成序列 from, from+/-1, \xe2\x80\xa6, to (与 from:to 相同)。
\n那么 seq(0, 3) 和 seq(0:3) 是不是相同?
\n我使用的是 Python 3,我想设置按钮的大小(以像素为单位)。
我想让它的宽度= 100像素,高度= 30像素,但它不起作用。
它比我预期的要大得多。
这是我的代码:
from tkinter import *
def background():
root = Tk()
root.geometry('1160x640')
btn_easy = Button(root, text = 'Easy', width = 100, height = 50)
btn_easy.place(x = 100, y = 450)
root.mainloop()
background()
