问题 I need to draw pattern along SVG path. I tried using SVG markers but there is a problem with their orientation along the path. Is there any alternative way to accomplish this? If yes, what should be my approach? The expected result is something like this- 回答1: The idea to use unicodes for drawing chain links came at once, as I read the question. I searched for a suitable unicode character for a long time. Could not use the unicode character of the chain. The unicode character of the U+26D3 ⛓

问题 I tested PyCharm and IDLE, both of them print the 7th number to a second line. Input: import numpy as np a=np.array([ 1.02090721, 1.02763091, 1.03899317, 1.00630297, 1.00127454, 0.89916715, 1.04486896]) print(a) Output: [ 1.02090721 1.02763091 1.03899317 1.00630297 1.00127454 0.89916715 1.04486896] How can I print them in one line? 回答1: There is np.set_printoptions which allows to modify the "line-width" of the printed NumPy array: >>> import numpy as np >>> np.set_printoptions(linewidth=np
