python foundation ===Excel processing library openpyxl

openpyxl is a third-party library that can handle Excel files in xlsx format.

 

Install:

pip install openpyxl

 

Read the following excel, as shown in the figure:

 

from openpyxl import load_workbook


wb = load_workbook("123.xlsx")

print(wb.get_sheet_names())
#>>>[Sheet111,Sheet222,Sheet333]

a_sheet = wb.get_sheet_by_name("Sheet111")

print(a_sheet.title)
#>>>Sheet111

a1 = a_sheet['A1']    
print(f'({a1.column}, {a1.row}) is {a1.value}')
#>>>3

a1_too =a_sheet.cell(row = 4, column = 2)
print(a1_too.value)
#>>>fvf


#Get the max column and max row 
print (a_sheet.max_row)
 # >>>6 
print (a_sheet.max_column)
 # >>>4

for row in a_sheet.rows:
    for cell in row:
        print(cell.value,end = '\t')
    print('\n')
    
'''

'''

#Get the data of a row or column 
for cell in list(a_sheet.rows)[3 ]:
   print (cell.value,end = " \t " )
 # >>>6 fvf None None


#Get cells in any interval 
for i in range(2, 4 ):
   for j in range(1, 3 ):
     print (a_sheet.cell(row=i, column=j).value,end = " \t " )
 # >>>4 None 5 None

 

 Write operations to files:
