格式化字符串(string formatting)是以指定输出参数格式和相对位置来“美化”字符串。输出参数格式包括数字的小数点位数、字符串大小写等,相对位置标注出被格式化的词是在句中的位置。比如 代码语言:javascript 代码运行次数:0 运行 AI代码解释 'It costs %.2f.' %(123.456) 其中%.2f 是 123.456 的输出参数格式,....
Python程序TypeError: not all arguments converted during string formatting解决方案 问题介绍 在Python中,当我们在使用字符串格式化时,有时会遇到TypeError: not all arguments converted during string formatting错误。这个错误通常发生在我们的字符串格式化表达式中包含了不正确的占位符或者占位符的数量与传入的参数不匹配...
Later in Python 2's history, a different style was introduced, called simplystring formatting(yes, that's the official name). Its very different syntax makes any Python string a potential template, inserting values through thestr.format()method. ...
# (2) b = b'hello'#直接指定这个hello是bytes类型 # (3) b = bytes('string',encoding='编码类型')#利用内置bytes方法,将字符串转换为指定编码的bytesb = str.encode('编码类型')#利用字符串的encode方法编码成bytes,默认为utf-8类型bytes.decode('编码类型'):将bytes对象解码成字符串,默认使用utf-8进...
