学习python过程中遇到的问题，在这里记录一下 下面是二维列表（数组）格式化输出的实例， 注意’\t’有加后会自动对齐：
a = [["学生学号","高等数学","高等物理","高等化学","程序语言","英文六级","个人平均成绩"], [201,'\t65','\t58','\t75','\t80','\t80','\t72'], [202,'\t92','\t66','\t85','\t85','\t87','\t83'], [203,'\t65','\t68','\t52','\t65','\t85','\t67'], [204,'\t38','\t78','\t98','\t36','\t58','\t62'], [205,'\t56','\t52','\t66','\t98','\t65','\t67'], [206,'\t85','\t66','\t74','\t56','\t85','\t73'], [207,45,30,58,47,96,55], [208,63,88,99,78,56,77], [209,54,91,32,85,85,69], [210,77,60,85,56,25,61], [211,76,56,83,25,35,55], [212,75,88,82,98,69,82], ["科目平均分数",66,67,74,67,69,0]] for i in range(14): for j in range(7): print(a[i][j], end="\t\t") print() # 打印一行后换行
