How can I perform operations on a group of arrays in Python?

Question

Having a group of arrays, eg

C3_mu, Cp3_mu, C4_mu, Cp4_mu, Cz_mu,
C3_beta, Cp3_beta, C4_beta, Cp4_beta, Cz_beta

I want to perform operations on them in a for loop.

I've tried the following:

channels = [C3_mu, Cp3_mu, C4_mu, Cp4_mu, Cz_mu,
            C3_beta, Cp3_beta, C4_beta, Cp4_beta, Cz_beta]

for chan in channels:
    chan = np.transpose(chan)  

but soon realized that, in this way, "chan" would be replaced by the array itself, and I can't see the right way of doing this.

Answer 1

您可以使用列表理解：

channels = [np.transpose(chan) for chan in channels]

Answer 2

Use enumerate()

for i, chan in enumerate(channels):
    channels[i] = np.transpose(chan)
