下面是一个Python函数示例,可以实现将单元格中的值进行分组:
def reverse_and_group(cell_value: str) -> str:
"""
Reverses the string and groups the characters in sets of three.
Example:
reverse_and_group('1234567890') -> '087, 654, 321'
"""
reversed_string = cell_value[::-1] # reverse the input string
grouped_string = [reversed_string[i:i+3] for i in range(0, len(reversed_string), 3)] # group the characters
return ', '.join(grouped_string) # join the groups with commas
该函数将输入的字符串进行反转,并将字符分组为三个一组。函数输出一个带有逗号的字符串,每个逗号后面是一个新的分组组合。例如,reverse_and_group('1234567890')将返回'087, 654, 321'字符串。
