我希望我的结果是：

Digit     Count     %
1         5738      29.4
2         3540      18.1
3         2342      12.0
4         1847      9.5
5         1559      8.0
6         1370      7.0
7         1166      6.0
8         1043      5.3
9         904      4.6

有什么建议吗？

Answer 1

您可以使用tabulate

>>> import tabulate 
>>> header = ['Digit', 'Count', '%']
>>> tabulate.tabulate([[i, num_count[i], num_count[i]/total_num*100] for i in range(1, 10)], headers=header, tablefmt='grid')

Answer 2

为什么不使用标签分隔符？

print("Digit", "\t", "Count", "\t", "%")
for i in range(1,10):
    print(i, "\t", num_count[i], "\t",format(num_count[i]/total_num*100,".1f"))

Answer 3

标签分隔符不适用于大数字。

解决方案是为print语句中的每个变量设置要打印的位数。就像在这个例子中一样：

for i in range(1,1000):
    print("%8d\t%s" % (i*10, i))

要说明选项卡分隔符失败的原因，如果运行此代码：

for i in range(1,1000):
   print("%s\t%s" % (i*10, i))

当它达到990时，你会看到格式化向右跳：

970 97
980 98
990 99
1000    100
1010    101

使用制表也是一种可能性，但这更直接，并提供了一个很好的解决方案。

Answer 4

除了使用制表符之外，您还可以使用str的.ljust方法填充空格以获得总共某些字符：

print(str(i).ljust(7, " "), 
      str(num_count[i]).ljust(7, " "), 
      format(num_count[i]/total_num*100,".1f"))

Answer 5

如果知道每列的宽度，可以使用字符串格式：

print("{0:<5s) {1:<5s} {2:<5s}".format("Digit", "Count", "%"))

for i in range(1, 10):
    print("{0:<5d) {1:<5d} {2:<3.2f}".format(i, num_count[i], format(num_count[i]/total_num*100,".1f")))

在此示例中，我们假设数字列最多包含5位数，计数列最多包含5位数，％列最多包含3位数字。小数点，小数点右边2位数。更多信息请访问：https://docs.python.org/2/library/string.html#format-string-syntax

Python，如何使用格式正确缩进我的结果？
