它不是那么漂亮,但是这张漂亮的表格打印效果很好:
import numpy as np
names=np.array(['H', 'B', 'D', 'A', 'I', 'C', 'F'])
a=np.array([[ 0., 2.4, 6.1, 3.2, 5.2, 3.9, 7.1],
[2.4, 0., 4.1, 1.2, 3.2, 1.9, 5.1],
[6.1, 4.1, 0., 3.1, 6.9, 2.8, 5.2],
[3.2, 1.2, 3.1, 0., 4., 0.9, 4.1],
[5.2, 3.2, 6.9, 4., 0., 4.7, 7.9],
[3.9, 1.9 , 2.8, 0.9, 4.7, 0., 3.8],
[7.1, 5.1, 5.2, 4.1, 7.9, 3.8, 0. ]])
def pptable(x_axis,y_axis,table):
def format_field(field, fmt='{:,.2f}'):
if type(field) is str: return field
if type(field) is tuple: return field[1].format(field[0])
return fmt.format(field)
def get_max_col_w(table, index):
return max([len(format_field(row[index])) for row in table])
for i,l in enumerate(table):
l.insert(0,y_axis[i])
x_axis.insert(0,' ')
table.insert(0,x_axis)
col_paddings=[get_max_col_w(table, i) for i in range(len(table[0]))]
for i,row in enumerate(table):
# left col
row_tab=[str(row[0]).ljust(col_paddings[0])]
# rest of the cols
row_tab+=[format_field(row[j]).rjust(col_paddings[j])
for j in range(1,len(row))]
print(' '.join(row_tab))
x_axis=['x{}'.format(c) for c in names]
y_axis=['y{}'.format(c) for c in names]
pptable(x_axis,y_axis,a.tolist())
印刷:

如果您希望 X 和 Y 轴相同,只需使用两个相同标签的列表来调用它。
