我正在尝试将同一函数的所有30次迭代存储在同一数据帧中。出于某种原因，我的数据帧只包含一次迭代。我需要对'结果'输出进行迭代吗？我的代码是：
df1 = pd.DataFrame.from_csv(filepath, index_col = None)
def find_peaks(x_data, y_data):
y_data = np.where(y_data > 5000, y_data, 0.1)
grad = np.diff(y_data)
peaks=[]
i = 0
while i < len(grad[:-1]):
if grad[i] > 0:
start = i
peak_index = find_peak(start, grad)
end = find_end(peak_index, grad)
area = np.trapz(y_data[start:end], x_data[start:end])
peaks.append((x_data[peak_index], y_data[peak_index], area))
i = end - 1
else:
i+=1
return peaks
for i in range(1,31):
result = find_peaks(df1['R'], df1['I {}'.format(i)])
df2 = pd.DataFrame(result)
print df2
out：
0 1 2
0 3053.6 105000.0 -5217775.735

10 2573.5 18009.0 -170745.690

17 799.2 32662.0 -305534.340
18 164.5 124000.0 -1579972.665
这只是一次迭代。有什么东西显而易见吗？
我可以创建一个数据帧并在for循环中打印它，如下所示：
for i in range(1,31):
result = find_peaks(df1['R'], df1['I {}'.format(i)])
df2 = pd.DataFrame(result)
print df2
