I'm a newbie in Python and I'd appreciate if you could help me with this problem.

I'd like to iteratively pass each column of a big DataFrame (156 rows x 451 columns) to a curve_fit function like this:

def func(x, a, c, d):
    return a*np.exp(-c*x)+d
popt, pcov = curve_fit(func, x, df[column])

Can anybody help me? Any idea/suggestion on alternative methods are welcome
