【问题描述】：
我有一些 python 代码，我想从 cmd 提示符运行，但是它不起作用，我的伙伴告诉我，如果我的代码中有这个语句：
if __name__ == '__main__':
xs, a0, a1, y0, y1, ys = encode(sys.argv[1])
np.set_printoptions(precision=6, suppress=True)
那么它应该能够运行。我将发布我的整个代码和我的命令提示错误，看看你们是否可以提供帮助

from numpy import linalg as LA
#Takes in a n value
def encode(n):
xA0 = np.zeros((n+3,1))

xStream = np.zeros((n+3,1))
#Creates a random x
for i in range(0, n):
xStream[i,0] = random.randint(0,1)

【问题讨论】：
-
你是如何安装python的，你是否允许它自己添加到你的系统路径中？
-
尝试在命令提示符中使用
py而不是python。 -
@Andy 我想我只是使用了一个安装程序，我可以检查一下 idk 吗？
-
@Andy 如果他安装了 Python
-
安装程序通常只安装到 C:/Python
