How to use python readlines method in random order

Question

How can one use the readlines() method to read a file in a random shuffled manner ie random.shuffle()

file = open(filename)
data = file.readlines()           
file_length =  len(data)

Answer 1

将它们放入带有lines = file.readlines()的列表中，然后列出列出的random.shuffle(lines) （导入random模块）。

Answer 2

You can store the entire file as a list of lines with:

f = open(filename)
data = f.read() # the whole file in one string
lines = data.split('\n')

Then use random to access lines.
