如果你在处理数值列表,可以使用numpy库。 python import numpy as np my_list = [1, 2, 3] my_string = ' '.join(np.array_str(my_list)) print(my_string) # 输出: [1 2 3] 方法6:使用ast.literal_eval() 如果你想要将列表转换为字符串,然后再将其转换回列表,可以使用ast.literal_eval()。
PIL.Image convert to numpy array 当使用PIL.Image读取图像时,如果直接使用numpy.array()转换会出现错误: lst = list() for file_name in os.listdir(dir_image): image = PIL.Image.open(file_name) lst.append(image) arr = numpy.array(lst)...
Flatten List Using NumPy Note that, NumPy doesn't come bundled with Python Installation you have to install it which can be done simply using Pip Installer. pip install numpy Once the installation is done you can run the code below,
First, though, we will need to install and import NumPy.# install numpy pip install numpy # import numpy import numpy as npNext, we will use np.array() function to convert the list of floats to integer.int_list = np.array(float_list).astype(int).tolist() print(int_list) # [1, ...
