(1)通过”import sys,sys.path.append('父目录的路径')“来改变,这种方法属于一次性的,只对当前的python解释器进程有效,关掉python重启后就失效了。 (2)直接修改环境变量: 在windows中是 “ set 变量=‘路径’ ” 例如: set PYTHONPATH=‘C:\test\...’ 查看是否设置成功用echo %PYTHONPATH%,而且进到pytho...
生成快递自提柜取件码随机数 现在,让我们使用Python生成快递自提柜取件码的随机数。取件码是一串数字组成的密码,用于验证用户的身份。我们可以使用随机数生成器来生成一个指定长度的取件码。 importrandomdefgenerate_pickup_code(length):"""生成指定长度的取件码"""code=""for_inrange(length):digit=random.ran...
导入模块通常在文件的最顶部进行,这是Python的常规做法。然而,在线程的上下文中,尤其是在多线程环境中,最好在使用模块之前进行局部导入,以减少因模块加载而导致的线程冲突和意外问题。 importthreadingdefthread_function():importnumpyasnp# 在子线程中局部导入result=np.random.rand(5)print(f"Random numbers from t...
In this code, you set the seed for NumPy’s random number generators. This function makes sure that each time you run this code, you’ll get the same set of random numbers. It’s here to make sure that your output is the same as the tutorial for comparison. In line 7, you generate...

So, in the Python program filemy_rand_int.pywe would import therandommodule to generate random numbers in this manner: my_rand_int.py importrandom Copy When we import a module, we are making it available to us in our current program as a separate namespace. This means that we will hav...
