A string in Python can be tested for truth value. The return type will be in Boolean value (True or False) my_string = "Hello World" my_string.isalnum() #check if all char are numbers my_string.isalpha() #check if all char in the string are alphabetic my_string.isdigit() #test ...
New macros: the Python header files now define the following macros: Py_ISALNUM, Py_ISALPHA, Py_ISDIGIT, Py_ISLOWER, Py_ISSPACE, Py_ISUPPER, Py_ISXDIGIT, Py_TOLOWER, and Py_TOUPPER. All of these functions are analogous to the C standard macros for classifying characters, but ignore the ...

Python中的BIF就是Built-in Functions,即内置函数的意思,内置函数就是为了方便程序员快速的编写脚本程序,Python提供了很多内置函数,只需要直接调用即可 想要查看Python中的内置函数,在IDLE中输入dir(__builtins__)(注:builtins前后分别是两个下横杠),如下所示:>>> dir(__builtins__) ['Ar ...
