Multiple graphs with different color lines and markers

I need to plot multiple graphs with different line colors and markers. I want number of graphs to be flexible and plot those automatically.

When I give and array of values to matplotlib.pyplot.plot to plot, it plots them with different colors. However, I couldn't find a way to also add markers on those plots. 

import matplotlib.pyplot as plt

x_axis = [[252.7, 252.7, 252.7, 252.7, 252.7, 252.7],
       [224.2, 224.2, 224.2, 224.2, 224.2, 224.2],
       [198. , 198. , 198. , 198. , 198. , 198. ],
       [179.2, 179.2, 179.2, 179.2, 179.2, 179.2],
       [148.2, 148.2, 148.2, 148.2, 148.2, 148.2],
       [124.7, 124.7, 124.7, 124.7, 124.7, 124.7],
       [ 97.4,  97.4,  97.4,  97.4,  97.4,  97.4],
       [ 81.3,  81.3,  81.3,  81.3,  81.3,  81.3],
       [ 62.4,  62.4,  62.4,  62.4,  62.4,  62.4]]
y_axis = [[ 98.986099 , 100.165872 ,  99.8226189, 100.563172 , 100.074811 ,
        100.603689 ],
       [ 99.9345974,  99.634039 , 100.126533 ,  99.99223  , 100.264707 ,
        100.165244 ],
       [ 99.97628  , 100.174231 ,  99.991863 ,  99.9305726, 100.114646 ,
        100.006637 ],
       [ 99.8629142, 100.068743 ,  99.7361936, 100.34242  ,  99.9061321,
        100.146376 ],
       [ 99.9580146,  99.9585485, 100.064912 ,  99.9304251, 100.135072 ,
        100.044364 ],
       [ 99.9656089, 100.022012 ,  99.910529 , 100.054065 , 100.194655 ,
         99.9474796],
       [ 99.916351 , 100.05248  , 100.045002 ,  99.8500087, 100.146954 ,
        100.097336 ],
       [ 99.8399431,  99.9708453, 100.040011 ,  99.9784648, 100.05224  ,
        100.262108 ],
       [ 99.9390728, 100.003478 , 100.062155 ,  99.9212035, 100.12125  ,
        100.09437  ]]

plt.plot(x_axis,y_axis)
plt.show()

Plot I get plt.plot assigns different color to each graph, but the markers are not shown.

I would like to see the markers too, and I want to have different marker styles with the same color as the graphs line

I am new to python, please help!

plt.plot(x, y, '-o')

did the job

Edit: in the argument '-o', '-' stands for solid line, 'o' stands for circle marker. Since x and y are arrays, and since there is no specification of color for markers and lines, python plots each graph in different color with solid line and circle marker.
