Perl印刷精确定位

Question

我有两个打印声明，一个接一个。

print("Number of cars");
printf("%10d","$somevariable");

print("Number of blue cars");
printf("%10d","$somevariable");

print("Number of  red cars");
printf("%10d","$somevariable");

我的问题是变量的值不会垂直对齐。它看起来像这样

Number of Cars       0
Number of blue Cars      0
Number of Red Cars       0

有没有办法将它们对齐到水平线上的某个点？例如，始终将所有内容打印在右侧80个空格处？

编辑：输出到终端。

干杯

Answer 1

在printf中包含标签：

printf("%-20s%10d\n","Number of cars", $somevariable)
printf("%-20s%10d\n","Number blue of cars", $someothervariable)

Answer 2

对于更复杂的布局，请考虑Text::SimpleTable，Text::Table或similar
