Python：用 Z7C2C714003D576477AFEZ8E8B8 格式化 Pandas dataframe 头

Question

I have made a Pandas dataframe from several NumPy arrays and tried to format columns heads using LaTex, but it looks awful. I'm working with Jupyter Notebook.

import numpy as np
import pandas as pd

Arrays (one instance out of five) look like this:

coeficientes = [0.5601, 0.3315, 0.2260, 0.1429, 0.0695]
coeficientes = np.array(coeficientes)

The dataframe:

tabla_resumen = pd.DataFrame({'$x_{n-i+1}$': submuestra1, 
                              '$x_{i}$': submuestra2, 
                              '$x_{n-i+1} - x_{i}$': diferencias, 
                              '$a_{n-i+i}$': coeficientes,
                              '$(x_{n-i+1} - x_{i})(a_{n-i+i})$': sumandos
                             })
tabla_resumen

The way it looks:

Are there any formatting options to make it look better?

Answer 1

Try this:

Function to convert to subscript

def get_sub(x):
    normal = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+-=()"
    sub_s = "ₐ₈CDₑբGₕᵢⱼₖₗₘₙₒₚQᵣₛₜᵤᵥwₓᵧZₐ♭꜀ᑯₑբ₉ₕᵢⱼₖₗₘₙₒₚ૧ᵣₛₜᵤᵥwₓᵧ₂₀₁₂₃₄₅₆₇₈₉₊₋₌₍₎"
    res = x.maketrans(''.join(normal), ''.join(sub_s))
    return x.translate(res)

Display subscript

print('H{}SO{}'.format(get_sub('2'),get_sub('4'))) #H₂SO₄
