二维数组的排序

result =[['7250','1'],['7510','2'],['7759','0'],['6523','33']]

copy_result = []

for item in result:
    copy_result.append([int(item[0]),item[1]])

print result
# output：
# [['7250', '1'], ['7510', '2'], ['7759', '0'], ['6523', '33']]

print copy_result
# output
# [[7250, '1'], [7510, '2'], [7759, '0'], [6523, '33']]

copy_result.sort()

print copy_result
# output
# [[6523, '33'], [7250, '1'], [7510, '2'], [7759, '0']]

back_result = []

for item in copy_result:
    back_result.append([str(item[0]),item[1]])

print back_result
# output
# [['6523', '33'], ['7250', '1'], ['7510', '2'], ['7759', '0']]

 

用int()和str()转换数据类型

二维数组的排序 sort()方法根据第一维的排序 

 

如果是逆序，用reverse()
