I have a file which contains a short DNA sequence and I want to open the file and then output a sentence which tells you what the dna sequence is and the length of the dna sequence. When I wrote my line of code however it printed the information on two different lines instead of as a sentence on one line.
The code below is what I tried:
#Open and read the file containing the dna sequence
file = open("dnaseq.txt")
dna = file.read()
#calculate the length of the dna sequence
dna_length = len(dna)
#print the sequence and the length of the sequence
print("sequence is " + dna + "the length of the sequence is " + str(dna_length))
The output from the code above gave me:
sequence is ATCGGATCA
and length is 9
So I then tried the following;
#use rstrip to remove the new line character
dna = file.read().rstrip("\n")
however this gave me the following:
sequence is and length is 9
what i want is a code that will give the following output:
sequence is ATCGGATCA and length is 9
>Solution :
is it ok
# Open and read the file containing the DNA sequence
with open("dnaseq.txt") as file:
dna = file.read().rstrip("\n") # Read the file and remove the newline character
# Calculate the length of the DNA sequence
dna_length = len(dna)
# Print the sequence and the length of the sequence in a single line
print("sequence is " + dna + " and length is " + str(dna_length))
