We can pass values to a conversion specification withprintf-style String Formatting: print("%s%s"%(current_year_message,current_year)) Copy Thecurrent_yearinteger is interpolated to a string:Year is 2018. We can also use thestr.format()function for concatenation of string and integer. 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...
String ConcatenationTo concatenate, or combine, two strings you can use the + operator.Example Merge variable a with variable b into variable c: a = "Hello"b = "World"c = a + b print(c) Try it Yourself » Example To add a space between them, add a " ": a = "Hello"b = ...

IntegerToString+str(num: int) : str+format_string(num: int) : str+string_concatenation(num: int) : str+f_string(num: int) : str 在上面的类图中,我们定义了一个名为IntegerToString的类,它包含了将整数转换为字符串的各种方法。 甘特图
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...

(String Concatenation:) The string is an immutable sequence data type. Concatenating immutable sequence data types always results in a new object. 字符串是不可变序列数据类型。 串联不可变序列数据类型总是会产生一个新对象。 Example 1:Strings are concatenated as they are, and no space is added betw...
Python - Efficient String Concatenation in Python (2016 edition)blog.mclemon.io/python-efficient-string-concatenation-in-python-2016-edition 结语 以上就是『Python 工匠』系列文章的第三篇,内容比较零碎。由于篇幅原因,一些常用的操作比如字符串格式化等,文章里并没有涵盖到。以后有机会再写吧。 让我们最后...
