The.splitlines()method splits a string at line boundaries, such as the newline characters (\n), carriage returns (\r), and some combinations like\r\n. It returns a list of lines that you can iterate over or manipulate further:

match()函数只检测要匹配的字符是不是在 string 的开始位置匹配,search()会扫描整个 string 查找匹配19.面向对象中__new__ 和 __init__ 区别__new__是在实例创建之前被调用的,因为它的任务就是创建实例然后返回该实例对象,是个静态方法。__init__是当实例对象创建完成后被调用的,然后设置对象属性的一些初始...

It will print complete string. Output would be Hello World!. What is the output of print str[0] if str = 'Hello World!'? It will print first character of the string. Output would be H. What is the output of print str[2:5] if str = 'Hello World!'?
deepcopy, method copy, slicing, etc.The copy() returns a shallow copy of list and deepcopy() return a deep copy of list. Python slice() function returns a slice object.A sequence of objects of any type(string, bytes, tuple, list or range) or the object which implements __getitem__...
For example, to convert a string to an integer, you can use theint()function: string_num='10'int_num=int(string_num)print(int_num) This will output: 10 Similarly, to convert an integer to a string, you can use the str() function: ...
Slicing also works on strings. Using what you learned above, try the exercises below. S = 'This is a string.' Exercise 7: Select ‘This’ from S. Be sure to run the cell S = ‘This is a string.’ first. Solution S[:4]
