7. 合并多个字符串为一个字符串 采用join() 方法可以将多个字符串合并为一个字符串。这相当于上一条技巧的反向操作。示例如下所示: list_of_strings = ['My', 'name', 'is', 'Chaitanya', 'Baweja']# Using join with the comma separatorprint(','.join(list_of_s
\# We start with joining each inner list into a single string joined = \[','.join(row) for row in input\_list\] \# Now we transform the list of strings into a single string output = '\\n'.join(joined) print(output) 这里我们.join()不是用一次,而是用了两次。首先,我们在列表推导...

模块1:Python基础 模块概述 欢迎来到本书的第一模块——Python基础!在这个模块中,我们将为您介绍Python编程语言最基础、最重要的概念和技术。 我们将从变量开始,通过学习运算符操作基本数据类型完成对于语句的学习,这是构建任何程序的基础。随后,我们将深入研究
list_of_strings = ['My', 'name', 'is', 'Chaitanya', 'Baweja']# Using join with the comma separatorprint(','.join(list_of_strings))# Output# My,name,is,Chaitanya,Baweja 1. 9. 检查给定字符串是否是回文(Palindrome) 反转字符串已经在上文中讨论过。因此,回文成为Python中一个简单的程序。
