Question

以pandas更改列名称，这将用于更改1列的名称。

import numpy as np
import pandas as pd
from openpyxl.workbook import Workbook
df = pd.read_excel(r'C:\Users\Desktop\testing.xlsx')
df.loc[((df.spin== 'sor') | (df.spin== r'f/r')), 'mtm' ] = df["mtm"] + df["wes"] *100000
df.rename(columns={'mtm':'mtm_new'}, inplace=True)
writer =pd.ExcelWriter(r'C:\Users\Desktop\output.xlsx')
df.to_excel(writer,'Sheet1')
writer.save()

Answer 1

df.loc[((df.SPIN == 'COR') | (df.SPIN == r'F/R')), 'MTM'] = (df["MARKET PRICE"] - df["TRADE PRICE"]) * (
df["QTY"] / 100)
df.rename(columns={'MTM': 'Market to Market'}, inplace=True)
reportName = "Output"
reportFileOut = rptDirPath + '\\' + reportName + '.xlsx'
writer = pd.ExcelWriter(reportFileOut)
df.to_excel(writer, 'Sheet1')
writer.save()

Answer 2

df = pd.read_excel（reportFileOut）df.sort_values（by = ['DOF']，inplace = True，ascending = False）writer = pd.ExcelWriter（reportFileOut）df.to_excel（writer，'Sheet1'）writer .save（）

Answer 3

df.loc [（df.SPIN =='COR'）| （df.SPIN =='F / R'）] df [“ MTM”] =（df [“市场价格”]-df [“交易价格”]）*（df [“数量]] / 100）这是实际公式，请检查-如果spin = F / R或COR，MTM =（[[MKT价格]-[交易价格]）*（[qty] / 100）

Answer 4

df.loc[((df.SPIN == 'COR') | (df.SPIN == 'F/R')), 'MTM' = ((df["MARKET PRICE"] -
df["TRADE PRICE"]) * (df["QTY"]/100))

这是实际公式，请检查-如果

spin = F/R or COR , MTM = ([MKT PRICE]-[trade price])*([qty]/100)

更改以熊猫为单位的列名称，该名称将用于更改1列的名称
