循环控制:continue, break, pass 有三种所谓的循环控制关键字:continue, break, pass。这些语句改变循环流，并允许程序在触发特定外部条件时退出或跳过部分循环。Break 如果在循环中存在break语句，则在满足条件时终止循环。string = 'hello, there'for i in string:if i == ',': break print(i)Out:hell...
price in products: # A if price not in unique_price_list: #B unique_price_list.append(price) return len(unique_price_list) products = [ (143121312, 100), (432314553, 30), (32421912367, 150), (937153201, 30) ] print('number of unique price is: {}'.format(find_unique_price...
split_words = sentence.split(', ') print(split_words) #输出['Hello', 'World!'] 11、字符串对齐操作 字符串rjust()、ljust()和center()对齐文本,通常通过插入空格来实现文本的对齐,也可以在方法中指定插入的字符。 string = "Hello" # rjust() 用 "*" 右对齐 print(string.rjust(10, '*')) ...
10.1 A list is a sequence Like a string, a list is a sequence of values. In a string, the values are characters; in a list, they can be any type. The values in a list are called elements or sometimes items. There are several ways to create a new list; the simplest is to enclos...
# Add the non-letters back to the start or end of the word. pigLatin.append(prefixNonLetters + word + suffixNonLetters) # Join all the words back together into a single string: print(' '.join(pigLatin)) 这个循环结束后,我们通过调用join()方法将字符串列表合并成一个字符串。这个字符串被...
words (list): A list of words (strings) in any order. Returns: corpus (list[tuple(str, int)]): A list of tuples where the first element is a string of a word in the words list, and the second element is an integer representing the frequency ...
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 use the slash to determine where to break the stri...
1、abs(x）Returns the absolute value of the number x or the modulus of a complex number.2、ascii(obj)Convert objects into ASCII representations, using escape characters to represent specific characters when necessary.3、bin(x)Converts the integer x to binary string representation.4、chr(x)...
