How do I automatically generate sheets using openpyxl in python?

import openpyxl:
# You must create an empty excel file named sample.xlsx in the same folder as the py file.
excel_document = openpyxl.load_workbook('same.xlsx')

sheet1 = excel_document.get_sheet_by_name('TEST')


initSet = ['0.1','0.2','0.3','0.4']

#list = [[0.139485297,0.2,0.3],[0.1,0.3,0.6],[0.2,1.4,0.3],[1.6,1.4,1.5,1,1,1,1,1]]

list = ["X", "Alpha", "Beta", "Gamma", "B/A", "C/A", "C/B"]


A =[0.3,0.5,0.7,0.4,0.2]
B =[0.1,0.3,0.5,0.7,0.9]
C =[0.1,0.4,0.2,0.1,0.5]

for i in range(0,len(list)):
    sheet1.cell(i+1,1).value = list[i]

for i in range(0,len(initSet)):
    sheet1.cell(1,i+2).value = initSet[i]
for i in range(0,len(A)):
    sheet1.cell(2,i+2).value = A[i]
for i in range(0,len(B)):
    sheet1.cell(3,i+2).value = B[i]
for i in range(0,len(C)):
    sheet1.cell(4,i+2).value = C[i]

excel_document.save("TEST.xlsx")
excel_document.close()
