如何给生成的结果中间加上逗号啊

import numpy as np
# 等差数列
print(np.arange(0.9, 1.1, 0.001))

变成列表再输出

 
import numpy as np
# 等差数列
n         =np.arange(0.9, 1.1, 0.001)
list1     =[]
for e in n:
    list1.append(float("%.3f"%e))
print(list1)

加个tolist()函数即可。

import numpy as np
print(np.arange(0.9,1,1,0.001).tolist())

import numpy as np
print(','.join(str(i) for i in np.arange(0.9, 1.1, 0.001)))
