1. Decision: Take the decision of how many rows and columns are required. The nested loops are used to print any pattern in python. For letting the user decide the size of the pattern, the “input()” function is used. 2. Iteration (i) Rows: outer loop is iterated for the number o...
Prime Number Pattern lns = 5 cur_no = 2 # Take 2 as the first num for ln in range(1, lns + 1): for position in range(1, ln + 1): while True: prime_no = True for ix in range(2, int(cur_no ** 0.5) + 1): if cur_no % ix == 0: prime_no = False break if ...

最后要讲到的re.sub()函数用来替换字符串里被匹配到的字串内容,类似于Word里面的替换功能,除此之外它还可以定义最大替换数(maximum number of replacement)来指定sub()函数所能替换的字串内容的数量,默认状态下为全部替换。re.sub()返回的值是字符串。 re.sub()函数的语法如下: a = re.match(pattern, replac...
You’ll read from the stdout of subprocess and use it in your wrapper Python program:Python magic_number.py from random import randint print(randint(0, 1000)) Okay, not really so magical. That said, it’s not the magic number generator that you’re interested in—it’s interacting with...
re.compile(strPattern[, flag]): 这个方法是Pattern类的工厂方法,用于将字符串形式的正则表达式编译为 Pattern对象。 第二个参数flag是匹配模式,取值可以使用按位或运算符'|' 表示同时生效,比如re.I | re.M 可以把正则表达式编译成一个正则表达式对象。可以把那些经常使用的正则 表达式编译成正则表达式对象,这样可...
