出现 invalid syntax 的错误通常是由于代码中存在语法错误导致的。可能是因为拼写错误、漏掉符号、错误的缩进等。以下是一个 Python 代码示例，可以生成包含100个随机整数的列表，并从后向前删除所有素数：import random 生成包含100个随机整数的列表 numbers = [random.randint(1, 100) for i in range(1...
4. 数组增加一个维度(2种方法:方法1:使用 np.expand_dims 函数(推荐);方法2:使用 reshape 函数) In [2]: a = np.random.randint(0, 30, (5, 2)) In [3]: a Out[3]: array([[24, 27], [9, 2], [20, 12], [23, 26], [27, 4]]) In [4]: a.shape Out[4]: (5, 2) In...
