如何使用制表来格式化带有千位分隔符和右对齐的数字

Sea*_*yen 8 python-3.x tabulate

我正在使用制表(https://pypi.org/project/tabulate/),我想用千位分隔符格式化数字列并将其右对齐。这就是我所做的,它没有正确对齐我的专栏。

import pandas as pd
rom tabulate import tabulate

df = pd.DataFrame([{'size':225612466, 'path': '/etc'}, {'size':66, 'path': '/home'}])
df['size'] = df['size'].apply(lambda x: "{:,}".format(x).rjust(15))
print(tabulate(df, headers='keys', tablefmt='psql', showindex=False))

+--------+-------------+
| path   | size        |
|--------+-------------|
| /etc   | 225,612,466 |
| /home  | 66          |
+--------+-------------+

我希望它是这样的:

+--------+-----------------+
| path   | size            |
|--------+-----------------|
| /etc   |     225,612,466 |
| /home  |              66 |

我猜缺少的参数tabulatenumalign="right",但你必须摆脱手动rjust将值更改为str

import pandas as pd
rom tabulate import tabulate

df = pd.DataFrame([{'size':225612466, 'path': '/etc'}, {'size':66, 'path': '/home'}])
print(tabulate(df, headers='keys', tablefmt='psql', showindex=False, numalign="right"))

给出输出:

+--------+-----------+
| path   |      size |
|--------+-----------|
| /etc   | 225612466 |
| /home  |        66 |
+--------+-----------+

如果您想保留千位分隔符,则必须使用以下命令保留格式并将字符串右对齐stralign

print(tabulate(df, headers='keys', tablefmt='psql', showindex=False, stralign="right"))
