Python string, numeric calculation, python string value Python is an object-oriented language, but it does not encapsulate standard classes into libraries like C ++. Instead, it further encapsulates the classes and functions of the language, such as print,

string, connecting with spaces Built-in functions to handle strings Copy Code code as follows: Len (str) #串长度 CMP ("My Friend", str) #字符串比较. First large, return 1 Max (' abcxyz ') #寻找字符串中最大的字符 Min (' abcxyz ') #寻找字符串中最小的字符 Conversion of String Oat (str) #变成浮点数, float ("1e-1″") results in 0.1 int (str) #变成整型, int ("12″") Results 12 Int (str,base) #变成base进制整型数, int ("11″,2")
