In Python, when usingprint(), you can use either the+operator for string concatenation or the,operator for separating arguments. However, using+with integers will raise a TypeError. To fix this, use the,operator to separate arguments, which will automatically convert integers to strings. Example:...
As with integers and floats, strings in Python can be added, using a process called concatenation, which can be done on any two strings. When concatenating strings, it doesn't matter whether they've been created with single or double quotes. >>> "Spam" + 'eggs' 'Spameggs' >>> print(...

>>> type(a) <type 'int'> Python是一门动态类型语言,和C、JAVA等语言不同,你无需手动指明变量的数据类型,根据赋值的不同你可以随意更改一个变量的数据类型,举例来说刚才我们把“整数”这个数据类型赋值给了a这个变量,现在我们再次赋值一个内容为test的"字符串"(String)数据类型给变量a,然后用type()函数来确...
1、整数(int) 1)基本数据类型提供了许多内部调用方法,如__add__,其效果和加法一样,即整数在做加法时,会内部调用__add__方法来完成。带下划线的方法用的少,所以其带下划线方法可以忽略。 2、str类型 1)下面列出部分API解释。 str.capitalize() Return a copy of the string with its first character capitali...
