Pandas dataframe - Formatting certain rows or cells to 2 d.p

pandas round column to 2 decimal places
pandas style format
pandas format numbers with commas
pandas round not working
pandas dataframe color cells
pandas round column to int
pandas round up column
pandas remove decimals

With the following dataframe, I would like to reformat the first two rows to 2 decimal places.

       A         B    C        D     E   F
0     68        45        1843.4    98
1  978.1             23              3    
2                                  
3          49889.2   80              

I have tried methods such as:

df.iloc[0:1,:].style.format("{0:.2f}")

For other projects I would also like to format certain cells, such as col B, index 3 to 49889.20 (2 d.p.), would a similar approach be used for this?

Thanks for any help

Additional Info: For some context to what I am doing, I am creating a mixed string/float dataframe to be printed via pylatex to LaTeX tex and PDF document (see PDF output below). The pdf prints the actual dataframe, so the PDF shows the dataframe identically as it would output in python. I would like to display the values to 2 d.p. as they are financial numbers. Preferably this will be edited in the dataframe, rather than in the pylatex process. i.e. so pylatex simply prints the dataframe. All calculations will have been completed before publishing PDF, so there is no issue turning the values into strings. Thanks.

Values are changed to strings, but it is possible:

df.iloc[:2] = df.iloc[:2].applymap('{0:.2f}'.format)
print (df)
      A        B      C        D      E    F
0  0.00    68.00  45.00  1843.40  98.00  nan
1  1.00   978.10  23.00     3.00    nan  nan
2     2      NaN    NaN      NaN    NaN  NaN
3     3  49889.2     80      NaN    NaN  NaN

EDIT: For custom function with try-except use:

def func(x):
    try:
        return '{0:.2f}'.format(x)
    except:
        return x

df = df.applymap(func)

pandas.DataFrame.round — pandas 1.1.0 documentation, Round a DataFrame to a variable number of decimal places. With a dict, the number of places for specific columns can be specified with the column names as � Pandas styling: Exercise-10 with Solution. Create a dataframe of ten rows, four columns with random values. Write a Pandas program to highlight the entire row in Yellow where a specific column value is greater than 0.5.

To build on @jezrael's answer, you can pass a dictionary for the columns:

import pandas as pd
import numpy
import string

#create some random data
df = pd.DataFrame({k:v for k,v in zip(list(string.ascii_uppercase[:5]), np.random.random_sample((5,5)))})

       A            B           C           D           E
0   0.995053    0.032561    0.556866    0.565944    0.613636
1   0.586174    0.932380    0.567946    0.277729    0.883482
2   0.210020    0.992571    0.626377    0.070947    0.723614
3   0.478476    0.866163    0.197633    0.621722    0.532891
4   0.743204    0.823418    0.616961    0.182829    0.642123

Then using, df.style.format({'B': "{:.2f}", 'D': '{:+.2f}'}) will yield:

       A         B          C         D        E
0   0.424395    0.23    0.960664    +0.96   0.992401
1   0.414769    0.57    0.664916    +0.73   0.850706
2   0.147415    0.88    0.873205    +0.12   0.33699
3   0.3742      0.28    0.496887    +0.74   0.885727
4   0.270247    0.67    0.501478    +0.10   0.113295

For completeness:

def conditional_formatter(value):
    return "{:.2f}".format(value) if not isinstance(value, str) else value

df.applymap(conditional_formatter)

Styling — pandas 1.1.0 documentation, You can apply conditional formatting, the visual styling of a DataFrame depending on the Styler.apply passes each column or row into your DataFrame one-at-a-time or the entire table at [2]:. import pandas as pd import numpy as np np.random.seed(24) df = pd. The row0_col2 is the identifier for that particular cell. Pandas have an options system that lets you customize some aspects of its behavior, here we will focus on display-related options. You may have experienced the following issues when using when you rendered the data frame: There’re too many columns/rows in the dataframe and some columns/rows in the middle are omitted on display.

Formatting rows in a pandas DataFrame is quite odd as the types are standardly defined per column, maybe changing this (orientation) might help. What might work is the .Round() method which can be called on DataFrames. https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.round.html

4 Methods to Round Values in Pandas DataFrame, Method 1: Round to specific decimal places – Single DataFrame column. Suppose that you have a dataset which contains the following values (with varying-length� The row0_col2 is the identifier for that particular cell. We’ve also prepended each row/column identifier with a UUID unique to each DataFrame so that the style from one doesn’t collide with the styling from another within the same notebook or page (you can set the uuid if you’d like to tie together the styling of two DataFrames).

Stylin' with Pandas, Pandas has a relatively new API for styling output. This article will show examples of how to format numbers in a pandas DataFrame and use some of leading dollar sign, add commas and round the result to 2 decimal places. In addition to styling numbers, we can also style the cells in the DataFrame. Extracting specific rows of a pandas dataframe ¶ df2[1:3] That would return the row with index 1, and 2. The row with index 3 is not included in the extract because that’s how the slicing syntax works. Note also that row with index 1 is the second row. Row with index 2 is the third row and so on.

We need a function that, given the value of a cell, returns the CSS� I always wanted to highlight the rows,cells and columns which contains some specific kind of data for my Data Analysis. I wanted to Know which cells contains the max value in a row or highlight all the nan’s in my data. and Pandas has a feature which is still development in progress as per the pandas documentation but it’s worth to take a look.
