问题1:可以使用循环来逐一实现行验证。首先,我们需要获取到行验证规则,然后分别计算每一行的和,并将结果与验证规则进行比较。代码如下:
- import openpyxl
- def validate_rows(filename):
- wb = openpyxl.load_workbook(filename)
- sheet = wb.active
- validations = [(5, ), (6, ), (15, ), (30, )] # 行验证规则
- for row in range(1, sheet.max_row + 1):
- if row > len(validations): # 如果超出了验证规则的范围,则退出循环
- break
- rule = validations[row - 1] # 获取当前行的验证规则
- total = sum(sheet.cell(row=row, column=col).value for col in range(1, sheet.max_column + 1)) # 计算当前行的和
- if total != rule[0]: # 判断和是否满足验证规则
- print(f"第{row}行验证失败!")
- wb.close()
- validate_rows("your_file.xlsx")

问题2:同样地,可以使用循环来逐一实现列验证。首先,我们需要获取到列验证规则,然后分别计算每一列的和,并将结果与验证规则进行比较。代码如下:
- import openpyxl
- def validate_columns(filename):
- wb = openpyxl.load_workbook(filename)
- sheet = wb.active
- validations = [(4, )] # 列验证规则
- for col in range(1, sheet.max_column + 1):
- if col > len(validations): # 如果超出了验证规则的范围,则退出循环
- break
- rule = validations[col - 1] # 获取当前列的验证规则
- total = sum(sheet.cell(row=row, column=col).value for row in range(1, sheet.max_row + 1)) # 计算当前列的和
- if total != rule[0]: # 判断和是否满足验证规则
- print(f"第{col}列验证失败!")
- wb.close()
- validate_columns("your_file.xlsx")
复制代码
问题3:在处理列验证规则时,可以使用eval()函数对字符串进行求值,从而实现计算等式两边的和并比较。代码如下:
- import openpyxl
- def validate_data(filename):
- wb = openpyxl.load_workbook(filename)
- sheet = wb.active
-
- def get_total(expression):
- # 根据表达式计算总和
- total = 0
- for col_letter in expression.split('+'): # 按+号分割每个列字母
- col_letter = col_letter.strip()
- col = ord(col_letter.upper()) - ord('A') + 1 # 将字母转换为列索引
- total += sum(sheet.cell(row=row, column=col).value for row in range(1, sheet.max_row + 1))
- return total
-
- while True:
- rule = input("请输入需要验证的列规则(输入N退出):")
- if rule.upper() == 'N':
- break
- try:
- left, right = rule.split('=')
- left_total = get_total(left)
- right_total = get_total(right)
- if left_total != right_total:
- print("验证失败!")
- else:
- print("验证通过!")
- except Exception as e:
- print(f"验证规则错误:{e}")
-
- wb.close()
- validate_data("your_file.xlsx")
