In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...

【Python】python之Character string 1、python字符串 字符串是 Python 中最常用的数据类型。我们可以使用引号('或")来创建字符串,l Python不支持单字符类型,单字符也在Python也是作为一个字符串使用。 >>> var1 = 'hello python' #定义字符串 >>> print(var1[0]) #切片截取,从0开始,不包括截取尾数...
标识符中有无效字符（invalid character in identifier）代码中出现了无法识别的字符，检查一下是否有多余字符或者中文字符。检查到不完整的字符串（EOL while scanning string litera）很多情况下是由于字符串两边的引号不统一。错误示例 print( 'hello'， 'world')错误原因：逗号为中文逗号报错信息：SyntaxError: invalid...
