Question

Fill in the following code:
# Open the file data.csv in read mode
data_file = XXXXXX

# This is a for loop where line is the variable name
# line will automatically be set to each line of the file data.csv
# and will be different at each iteration of the loop
for XXXX in data_file:
# Create a list called columns, that contains the 4 elements of the row
columns = line.rstrip(XX).split(XX)
# assign the 0th column to the variable species
species = XXXXXX
# assign the 1nd column to the variable name
name = XXXXXX
# assign the 2st column to the variable sequence
sequence = XXXXXX
# assign the 3rd column to the variable expression
expression = XXXXXX
# This is an if condition that prints the contents of the variable name
# if the name of the species is either Drosophila yakuba or
# Drosophila ananassae
if XXXXXXXXXXXXXXX:
print(name)

# Close file
XXXXXXXX

Answer 1

CODE:

# Open the file data.csv in read mode
data_file = open("data.csv",'r')

# This is a for loop where line is the variable name
# line will automatically be set to each line of the file data.csv
# and will be different at each iteration of the loop
for line in data_file:
    # Create a list called columns, that contains the 4 elements of the row
    columns = line.rstrip().split(",")
    # assign the 0th column to the variable species
    species = columns[0]
    # assign the 1nd column to the variable name
    name = columns[1]
    # assign the 2st column to the variable sequence
    sequence = columns[2]
    # assign the 3rd column to the variable expression
    expression = columns[3]
    # This is an if condition that prints the contents of the variable name
    # if the name of the species is either Drosophila yakuba or
    # Drosophila ananassae
    if name=="Drosophila yakuba" or name=="Drosophila ananassae":
        print(name)

# Close file
data_file.close()
