Python’s random module makes it extremely easy to generate random DNA bases.
import random dna = ["A","G","C","T"] #output a random base print(random.choice(dna))
Now to generate a specific number of random bases, all we have to do is use Python’s range function:
import random
dna = ["A","G","C","T"]
#initialise empty string
#this is where the bases will be added as they are generated
random_sequence=''
# We'll create a string of 100 random bases
for i in range(0,100):
random_sequence+=random.choice(dna)
print(random_sequence)
