确定准确时间的算法的实现问题

0

从一些api我得到格式的当前时间 - 1589468357。

通过实验，我意识到这是从 1970 年开始计算的秒数 ..

问题：

知道这个数字，如何尽可能便宜地确定准确时间

起初我想引入某种常数，即从 2020 年初开始的秒数，然后从得到的数字中，取这个常数并进一步划分结果，但我必须考虑闰年等.，但我不高）

还想查找当天开始的秒数，但意识到该数字也可以表示早于当天的日期..

有任何想法吗？

正则表达式在字符串中搜索构造“将数字分配给变量”

2

让有这样的行：

b = 1
b = [1, 2, 3]
b = {1, 2, 3}

我只想找到b = 1，即任意数量的缩进，任意长度的名称，任意长度的数字，但只有一个数字，列表中出现的数字不适合。

试过：

(\s*\D*\w+).*=.*?[^[]*(\d+)

但即使使用贪婪搜索，分组时的结果，例如：

b = [1, 2, 3]看起来像这样：b = [1, 2, 3也就是说，它仍然爬过。

告诉我如何在第一个条目处[停止搜索{，因为那样就不一样了。

如何为 Qt Designer 固定图像？

1

Qt Designer中有这段代码：

self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setEnabled(True)
self.label.setGeometry(QtCore.QRect(10, 10, 441, 481))
self.label.setText("")
self.label.setPixmap(QtGui.QPixmap("../../image.png"))
self.label.setScaledContents(True)
self.label.setObjectName("label")

也就是说，只是在labelvia中显示图像QPixmap，但问题是使用图像的相对路径，当移动编译的程序时，图片丢失，这是合乎逻辑的，但它会丢失，我会在某个地方填充这个程序.

问题是 - 是否可以将图像分配给程序，以便例如以编译形式 ( )pyinstaller保存？

生成器函数的不可理解的行为

0

有一个生成器函数，n如果它大于某个数字，则该函数调用自身n - 1并将该数字乘以2的值写入生成器。以此类推，直到数字小于或等于某个数，那么就已经可以写下它的平方了。只是现在她不叫自己，谁来告诉你为什么？

def pip(n):
    if n > 10:
        pip(n - 1)
        yield n * 2
    else:
        yield n ** 2

x = pip(11)
print(next(x))

删除 QTextView 行时字体更改

3

一切正常，唯一的问题是在两个字段QTextView中光标（垂直棒）的大小都小于透明文本的大小placeHolderText。

当您键入时，光标大小会标准化，但是если удалить все написанное，字体会变清晰становится маленьким（之后它不会恢复到正常的字体大小）。

谁会提示，它可以连接什么？

有这个代码：

cursor = connection.cursor()
f = cursor.fetchall()
print(f)

我试图从变量中获取所有内容cursor，但我得到了[]，这可能是什么原因？

[:] 和 .copy() 有什么区别？

12

面对这样的情况，有一个清单：

a = [1, 2, 3]

我想得到它的副本，使新的переменную唯一，这样它就不会引用旧的地址。我知道两个本质上做同样事情的结构：

b = a[:]

和

b = a.copy()

它们都是正确的，并且会给出相同的结果，但是它们之间有根本的区别吗？

Essence：单击时ADD，会打开一个窗口，您可以在其中输入注释的标题和文本。

我想得到的是：这样当您单击从Main 类调用的MessageWindowConfirm类的打开窗口时， MessageWindow 类的两个窗口中的文本将写入此Main类中的变量，即

self.title = lineEdit из MessageWindow

self.text = textView из MessageWindow

也就是说，当用户输入一个注释并单击确认时，该注释的标题和文本将保存在类中Main以供进一步工作。

ModuleNotFoundError：没有名为“异常”的模块/ ModuleNotFoundError：没有名为“docx”的模块

您需要打开一个 Microsoft Word 文件（.doc、.docx）进行读写操作：

pip install docx
pip install python-docx

这两个命令都出现以下错误：

ModuleNotFoundError: No module named 'docx'

我也尝试使用 PyCharm 本身：

import docx
from docx import Document

点击弹出错误直接从 PyCharm 安装包，得到这个：

ModuleNotFoundError: No module named 'exceptions'

如果需要，这是代码

from docx import Document


file = r'C:\Users\fsoci\Desktop\d.docx'#input('full path: ')

def getText(filename):
    doc = Document(filename)
    fullText = []
    for para in doc.paragraphs:
        fullText.append(para.text)
    return '\n'.join(fullText)

print(getText(file))

无论我重新安装docx和python-docx多少次，仍然有这些错误，可能是什么问题？？

找到下一个具有相同数字的较小数字

3

输入是一个由n位组成的数字，你需要找到前一个数字相同的数字，例如：12354 - 12345, 21 - 12, 511 - 151。如果找不到，输出-1 ，例如：9 - (-1), 222 - (-1), 500 - (-1)因为零是微不足道的，这与条件相矛盾。

import itertools as iter

def next_smaller(number):
    digits = [digit for digit in str(number)]
    all, l = list(iter.permutations(digits)), -1
    for i in range(len(all)):

            l = int(''.join(all[i])) if int(''.join(all[i])) > l else l

这通常会减慢 10 ^ 9 个数字

肯定会有很多数字，你需要找到其中最大的——也就是最接近原始数字的

据我了解，这就是对所有数字或其组合进行排序所需的时间，如 1 个示例所示，有助于简化代码。
