For path specification, python uses forward slashes. Hence if you are working with a file, the default path for the file in case of Windows OS will have backward slashes, which you will have to convert to forward slashes to make them work in your python script. 对于窗口的路径C:\folderA\...
By default, Python source files are treated as encoded in UTF-8. In that encoding, characters of most languages in the world can be used simultaneously in string literals, identifiers and comments — although the standard library only uses ASCII characters for identifiers, a convention that any ...

Similarly, in order to access 2nd last element use -2 as index, for 3rd last use -3 and so on, i.e., for ith element from the last use -ith as the index. So that settles the generalization for accessing each character from both forward and backward side in a string. Note that ...
It is possible in Python to define a function in which one or more arguments can not accept their value with keywords. Such arguments are called positional-only arguments.To make an argument positional-only, use the forward slash (/) symbol. All the arguments before this symbol will be ...
Notice the slash (/) after the parameter. What does it mean?Note: For an in-depth discussion on the / notation, see PEP 457 - Notation for Positional-Only Parameters.It turns out that while the one parameter of float() is called x, you’re not allowed to use its name:...
You’ve already defined the constant BASE_DIR in settings.py, and it points to your project’s root directory. Next, you join the path with the forward slash operator (/) from pathlib to point to the templates/ directory and add it to the "DIRS" list. Now, when you visit localhost:...
assert escapeSlash == 'The character / is a forward slash' //多行支持 def multilineSlashy = /one two three/ assert multilineSlashy.contains('\n') //含站位符使用支持 def color = 'blue' def interpolatedSlashy = /a ${color} car/ ...
“7/11/2019”. You can see that it starts with the month, followed by the day of the month, and ends with a 4 digit year. Each part is separated by a forward slash. The datetime library has a special encoding you use to tell it which parts are which. A few examples that we ...
