The question title explains everything. I would like to plot a dataframe. Say, 7 rows 3 columns. I would like to plot every column with random colors. How can I do that?

Since you don't have a huge dataset, you can create a dictionary called color_dict and lookup the colors from it when plotting.
import pandas as pd
data = {
'time0': [41, 28, 33, 34, 38, 31, 37],
'time1': [48, 26, 39, 33, 58, 41, 43],
'time2': [53, 30, 51, 37, 48, 49, 53]
}
df = pd.DataFrame(data=data)
import random
color_dict = {}
for idx in range(df.shape[1]):
r = random.random()
b = random.random()
g = random.random()
color = (r, g, b)
color_dict[idx] = color
colors = [color_dict.get(x) for x in range(df.shape[1])]
import matplotlib.pyplot as plt
for idx in range(df.shape[1]):
plt.plot(df.iloc[:,idx], color=colors[idx])
