Python program to make a diamond pattern using for loop Choose how many rows and columns to use. The number of rows and columns is a common structure for printing any pattern. To print any pattern, we must use two loops; in other words, we must use nested loops. The number of rows a...
It gives the path to the Python executable that will run our program. In line two, we assign our name to a variable called user. Next, we print the result, joining the text together using the concatenation operator, a plus sign, to join our variable to the rest of the text. Let's ...

pattern即为我们要匹配的正则表达式模式,string为要匹配的字符串,flags为标志位,用来控制正则表达式的匹配方式,如是否区分大小写,是否多行匹配等等,flags为可选项,不是很常用。 举例说明: >>> import re >>> test = 'Test match() function of regular expression.' >>> a = re.match(r'Test',test) >>...
parse_args() print(f"Starting timer of {args.time} seconds") for _ in range(args.time): print(".", end="", flush=True) sleep(1) print("Done!") The timer program uses argparse to accept an integer as an argument. The integer represents the number of seconds that the timer should...
