上面的占位符都是单个变量或常量,在Python中多个占位符使用“%(value1,value2…)”来表示,如下: # 多个占位符 name = '李四' age = 18 print ( '我的名字是%s,我的年龄是%d岁了' %( name, age ) ) # 打印结果如下: 我的名字是李四,我的年龄是18岁了 1. 2. 3. 4. 5. 6. (*需要注意的是...
If the variable is not found in either namespace, Python will raise an error. This process of searching for variables is known as the “LEGB” (Local, Enclosing, Global, and Built-in) rule in Python. In cases where a function needs to modify the value of a global variable, the “glo...

param = 10 def main(): print("param_value:%d\t param_id:%d" %(param, id(param))) if __name__ == "__main__": main() PYTHON 变量默认是全局变量,在不申明 global param 的情况下,程序可以正确输出: “param_value:10 param_id:140704526292288” 但是当 param 被 global 申明,结果好像不一...
由于Python的time模块实现主要调用C库,所以各个平台可能有所不同. UTC(Coordinated Universal Time,世界协调时)亦即格林威治天文时间,世界标准时间。在中国为UTC+8。DST(Daylight Saving Time)即夏令时。 时间戳(timestamp)的方式:通常来说,时间戳表示的是从1970年1月1日00:00:00开始按秒计算的偏移量。我们运行“...
v1="Value1" f1() 运行的结果是: File "D:\workplace\python\test\test.py", line 2, in f1 print(v1) UnboundLocalError: local variable 'v1' referenced before assignment 按上面说法,预想到的f1()中第一个print(v1)打印出“local”的结果并未出现,我们下一步想到的是即使不打印局部也应该去寻找全...
