Use of transparent channelsPutalpha (Alpha)This method is a magical way, you can write a picture (and the original size of the same) to the original image of the transparent channel, without affecting the normal display of the original picture, can be used for information hiding oh. Of course, the premise is that the originalThe initial picture has a transparent channel. However, even if it is not much of a relationship, because there is the CONVERT function provided by PIL, you can convert a pi

Python is already installed on the machine, and the environment variables are well configured Write Good xx.py file Install Pywin32. It is important to note that Pywin32 has 32-bit and 64-bit points. You can enter Python at the command prompt to see the version of Python and whether it is 32-bit or 64-bit (my Python is 2.7.9 32-bit) To install Pyinstaller, simply extract Pyinstaller to any location and then go to Pyinstaller setup.py location at the command prompt, enter setup.py instal

I'll have to admit that... it was so easy to use $ _ file for file uploading in PHP. Trying to switch to python from PhP (for varous reasons including shared Configuration between web and background processes, etc ). started looking at web. PY (with other alternatives as well) and, surprisingly, found that the webpy's document is nothingMore than... Nothing. Even the "receipts" in "cookbook" are for those who don't need them. So I'm lost totally

Set is similar to Dict and is a set of keys, but does not store value>>> s = set([1, 2, 3])>>> s{1, 2, 3}Note that the parameter passed in [1, 2, 3] is a list, and the display {1, 2, 3} only tells you that the set has 3 elements, the order of the display does not indicate that the set is ordered.Repeating elements are automatically filtered in set:>>> s = set([1, 1, 2, 2, 3, 3])>>> s{1, 2, 3}You can add(key) add elements to a set by means of a method, and you can add them repeatedly, but with no

', 'b', 'c', 'hello']）改变时会影响到c；d是深拷贝，完全不受a的影响? ===========浅拷贝是指拷贝的只是原对象元素的引用，换句话说，浅拷贝产生的对象本身是新的，但是它的内容不是新的，只是对原对象的一个引用。这里有个例子 Alist=[[1, 2], 3, 4]Blist = alist[:] #利用切片完成一次浅拷贝ID (alist)3084416588LID (blist)3084418156LAlist[0][0] = 5Alist[[5, 2], 3, 4]Blist[[5, 2], 3, 4] 可以看到，浅拷贝生产了一个新的对象bList,但是aList的内容确实对aList的引用，所以但改变aList中值的时候，bList的值也跟着变化了。但是有点需要特别提醒的，如果对象本身是不可变的，那么浅拷贝时也会产生两个值，见这个例子： Alist = [1, 2]Blist = alist[:]Blist[1, 2]Alist[1,
