Let’s look at a couple of common sequence operations on strings. 让我先定义一个字符串。 Let me first define a string. 让我们来看看“Python” Let’s just go with "Python." 同样,如果我想知道我的字符串有多长,我可以使用len函数。 Again, if I wanted to find out how long is my string,...
import random import string import cache def random_string(length): s = '' for i in range(length): s = s + random.choice(string.ascii_letters) return s cache.init() for n in range(1000): while True: key = random_string(20) if cache.contains(key): continue else: break value = ...
Functionally, this is the same as writing it all out as one single string:r"\[(.+)\] [-T:+\d]{25} : (.+)". Organizing your longer regex patterns on separate lines allow you to break it up into chunks, which not only makes it more readable but also allow you to insert comment...
It passes that Tcl command string to an internal _tkinter binary module, which then calls the Tcl interpreter to evaluate it. The Tcl interpreter will then call into the Tk and/or Ttk packages, which will in turn make calls to Xlib, Cocoa, or GDI....
def say_hello(name): return f"Hello {name}" def be_awesome(name): return f"Yo {name}, together we're the awesomest!" def greet_bob(greeter_func): return greeter_func("Bob") Here, say_hello() and be_awesome() are regular functions that expect a name given as a string. The gree...
addrString,cidrString = sys.argv[1].split('/') The string split method always returns a list. In this case, our list will have two values: the IP address (which we put into the addrString variable) and the CIDR notation (which we put into the cidrString variable. We tell split to...

In Python 2.x, the variable name e gets assigned to Exception() instance, so when you try to print, it prints nothing. Output (Python 2.x): >>> e Exception() >>> print e # Nothing is printed!▶ The mysterious key type conversionclass SomeClass(str): pass some_dict = {'s':...
