For the .format() method to work, you must provide replacement fields using curly brackets. If you use empty brackets, then the method interpolates its arguments into the target string based on position.You can manually specify the interpolation order by referencing the position of each argument...
# In python 3.x print(5/2) Two point five 功能xrange()不再支持 在Python 2.x 中,如果我们想要生成一个范围内的数字列表,我们可以使用range函数返回一个列表,例如range(2)将返回列表[0,1],或者使用xrange()函数,该函数不返回列表,但返回一个迭代器对象,您可以在其上进行迭代并获得数字的范围。简单来...
result = ', '.join(re.escape(elem) for elem in my_list) print(result) 在这段代码中,使用re.escape()函数对每个元素中的特殊字符进行转义,然后使用join()方法将结果列表中的元素连接起来,中间用逗号和空格分隔。最终输出结果是字符串"hello\, world, python, special\: characters"。
