如何使用熊猫格式化Excel单元格？

Question

Can you "format cell" using pandas?

I have a column that has large numbers so excel auto the numbers as exponents. I want it so the decimal place will be "0" for the column so I can have a whole number.

Ex. On excel

     A
27782239216
3.93479E+11<---
97336460903
6.40211E+12<---
5.58299E+12<---

I want to set the decimal place in column A to be 0

Ex. On excel

     A
27782239216
393479119893<---
97336460903
6402108304702<---
5582993267823<---

Is there a add format function for pandas I can use?

Answer 1

use below numpy code if there arre integers only:

import numpy as np
dataFrame['ColumnName'] = dataFrame['ColumnName'].astype(np.int64)

Answer 2

you could change display format like below

pd.options.display.float_format = '{:20,.2f}'.format

or

df['A'].apply(lambda x: '%.1f' % x)
