1.将list中的数据写入到excel文件中
利用python包numpy（实现方式应该有许多种，这里只是记录成功实现的一种）中的savetxt
局限性：要保存的list可以为[1,2,3,4,5]这种形式，也可以是[[1,2,3,4,5],[6,7,8,9,10],[11,12,13,14,15]]这种形式，但如果是第二种情况（list中每个元素都为list）时，list中的每个list所含有元素个数要相同，这是因为该方法需要先将python的list数据转化为array类型
import numpy as np
# python list that is needed to be save in the csv file
data_list = [,,,,,,,]
print type(data_list)
# convert list to array
data_array = np.array(data_list)
print type(data_array)
# saving...
np.savetxt('data.csv',data_array,delimiter=',')
print 'Finish saving csv file'
结果：
<type 'list'>
<type 'numpy.ndarray'>
Finish saving csv file
import numpy as np
# python list that is needed to be save in the csv file
data_list = [[1,2,3,4,5,6,7,8],[9,10,11,12,14,1,2,3],[4,3,2,1,3,6,7,8]]
print type(data_list)
# convert list to array
data_array = np.array(data_list)
print type(data_array)
# saving...
np.savetxt('data.csv',data_array,delimiter=',')
print 'Finish saving csv file'
结果
<type 'list'>
<type 'numpy.ndarray'>
Finish saving csv file
