我需要遍历pandas df的每一行并将其转换为逗号分隔的字符串.
例:
df3 = DataFrame(np.random.randn(10, 5),
columns=['a', 'b', 'c', 'd', 'e'])
a b c d e
0 -0.158897 -0.749799 0.268921 0.070035 0.099600
1 -0.863654 -0.086814 -0.614562 -1.678850 0.980292
2 -0.098168 0.710652 -0.456274 -0.373153 -0.533463
3 1.001634 -0.736187 -0.812034 0.223062 -1.337972
4 0.173549 -0.576412 -1.016063 -0.217242 0.443794
5 0.273695 0.335562 0.778393 -0.668368 0.438880
6 -0.783824 1.439888 1.057639 -1.825481 -0.770953
7 -1.025004 0.155974 0.645023 0.993379 -0.812133
8 0.953448 -1.355628 -1.918317 -0.966472 -0.618744
9 -0.479297 0.295150 -0.294449 0.679416 -1.813078
我想得到每一行:
'-0.158897,-0.749799,0.268921,0.070035,0.099600'
'0.863654,-0.086814,-0.614562,-1.678850,0.980292' …
