We can use thepython stringjoin()function to join a list of strings. This function takesiterableas argument and List is an iterable, so we can use it with List. Also, the list should contain strings, if you will try to join a list ofintsthen you will get an error message asTypeError...
re,mi'在这里，我们strings用逗号 ( ,)连接列表的每个元素，并调用.join()它而不是strings列表。
# 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) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 这里...

join()方法可以将字符串列表组合成一个字符串,下面的代码片段中,我使用,将所有的字符串拼接到一起: AI检测代码解析 list_of_strings = ['My', 'name', 'is', 'Chaitanya', 'Baweja'] # Using join with the comma separator print(','.join(list_of_strings)) ...
现实生活中文字随处可见,编程语言中则用字符串来表示,字符串是Python中最常用的数据类型。想想在没有图形化界面的时代,几乎都是对字符串和数字的处理,衍生到后来的网页、Windows应用程序等都能看到对字符串的操作。还有每个国家都有不同的语言,而字符串有不同的字符串编码来表示。越容易小瞧的反而越重要 ...
Python 3.6 引入了f-strings,除了用大括号代替了%s,表达式直接放在大括号里面,与字符串插值类似。像原始字符串一样,F 字符串在起始引号前有一个f前缀。在交互式 Shell 中输入以下内容: >>>name ='Al'>>>age =4000>>>f'My name is{name}. Next year I will be{age +1}.''My name is Al. Next ...
# Using join with the comma separator print(','.join(list_of_strings)) # Output # My,name,is,Chaitanya,Baweja 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。 my_string = "abcba" m if my_string == my_string[::-1]: print...
相反的操作是.join(),因此您可以在要用于将可迭代字符串连接在一起的字符串或字符上调用它: >>> >>> strings = ['do', 're', 'mi'] >>> ','.join(strings) 'do,re,mi' 在这里,我们strings用逗号 ( ,)连接列表的每个元素,并调用.join()它而不是strings列表。 练习:“通过加入提高可读性”显示...
