创建一个计数器，该计数器在dataframe中值为1时递增

import pandas as pd

df = pd.DataFrame({'Value': [1, 1, 1, 2, 1, 3, 1]})

def increment_counter(row):
    if row['Value'] == 1:
        increment_counter.counter += 1
    return increment_counter.counter

increment_counter.counter = 0

df['Counter'] = df.apply(increment_counter, axis=1)

print(df)
