To learn some different ways to remove spaces from a string in Python, refer toRemove Spaces from a String in Python. A Python String object is immutable, so you can’t change its value. Any method that manipulates a string value returns a new String object. The examples in this tutorial...
四、整数的附加方法int 类型实现了 numbers.Integral abstract base class。此外，它还提供了其他几个方法:int.bit_length()返回以二进制表示一个整数所需要的位数，不包括符号位和前面的零n = -37bin(n)'-0b100101'n.bit_length()6更准确地说，如果 x 非零，则 x.bit_length() 是使得 2**(k-1) <...
常用函数: string.split(separator),把字符串按照 separator 分割成子字符串,并返回一个分割后子字符串组合的列表; string.strip(str),去掉首尾的 str 字符串; string.lstrip(str),只去掉开头的 str 字符串; string.rstrip(str),只去掉尾部的 str 字符串。 列表和元组 列表和元组,都是一个可以放置任意数据类型...
