This CSV file contains the results of my investments.
The column containing the profit/loss is the column named back
And I want to test it like this:
Let's assume that I want to see the total profit only for the investments I would make if according to some filters this investment pattern was profitable in previous records.
Example:
The 51st investment is 'market_name' → Over/Under 2.5 Goals , 'runner_name' → Under 2.5 Goals and 'odds' → 1.24
So I want to sum the profit/loss of 50th previous investments if they have these same filters, if the sum of these filters is greater than zero, then I make investment 51.
And so on in each of the lines, 100th investment, I see if the previous 99 investments filtering the cited options will be profitable, if so, I add the back column of 100th to the list for final sum.
So I created this code:

import pandas as pd

df = pd.read_csv(test.csv')
df = df[df['result'].notnull()]

matches = []

for number in range(len(df)):
    try:
        dfilter = df[:number]
        filter = dfilter[(dfilter['market_name'] == df['market_name'][number+1]) & (dfilter['runner_name'] == df['runner_name'][number+1]) & (dfilter['odds'] == df['odds'][number+1])]
        back_sum = filter['back'].sum()
        if back_sum > 0:
            matches.append(df['back'][number+1])
    except:
        pass

print(sum(matches))

But the final sum is delivering a result that does not match my real results where I invest.
I can't find where the flaw is in the code because it looks correct to me visually.

切片df[:number]意味着取第个元素。当引用当前行时，必须使用number，而不是number+1。这可以检查，例如，打印df[:3]并获取第三行之前的所有行。
但是如果使用loc，则通过切片的操作将不会达到，而是包含（您不应该忘记这一点）。也就是说，使用df.loc[：3，：]将选择行，包括第三行。
也就是说，您需要：

for number in range(len(df)):
    try:
        dfilter = df[:number]
        filter = dfilter[(dfilter['market_name'] == df['market_name'][number]) &
                         (dfilter['runner_name'] == df['runner_name'][number]) & (dfilter['odds'] == df['odds'][number])]

        back_sum = filter['back'].sum()
        if back_sum > 0:
            matches.append(df['back'][number])
    except:
        pass

如果 Dataframe 很大，循环就会很慢。我可以推荐列表理解，它比循环快很多倍。下面我做了一个列'invest'，其中，根据back_sum，值将是True或False。

df = pd.read_csv('test.csv')

#df = df[df['result'].notnull()].reset_index(drop=True)
"""
is whether all indexes of the original dataframe are needed,
if not, then you can add this line and use the filtered dataframe(if you need a filtered dataframe,
uncomment this line df = df[df['result'].notnull()].reset_index(drop=True))
"""

def my_func(i):
    dfilter = df[:i]
    filter = dfilter[(dfilter['market_name'] == df['market_name'][i]) &
                     (dfilter['runner_name'] == df['runner_name'][i]) & (dfilter['odds'] == df['odds'][i])]
    back_sum = filter['back'].sum()
    aaa = True
    if back_sum <= 0:
        aaa = False

    return aaa

df['invest'] = [my_func(i) for i in range(len(df))]
