使用python语言和panda，当我的if语句为真时，我如何操作一个现有的CSV单元格，使其单元格值总是加1？
>while True > if xxx = TRUE > "open existing CSV and take the value of A1 and increment by +1"

试试这个
import pandas as pd A = list(range(10)) B = [a%3==0 for a in A] df = pd.DataFrame({'A':A, 'B':B}) df['A+1 if B True'] = df['A'] + df['B'] * 1
