Answer:
Hence the complete implementation of python code that reads two files and merges them together.
def merge_file(past_file_path,proposed_file_path, merged_file_path):
past_file_contents=load_file(past_file_path)
proposed_file_contents=load_file(proposed_file_path)
proposed_customer_name = []
for row in proposed_file_contents:
proposed_customer_name.append(row[1])
with open(merged_file_path,'w') as outputf:
outputf.write("Customer Number, Customer Name, Address\r\n")
for row in proposed_file_contents:
line = str(row[0]) +", " + str(row[1]) + ", " + str(row[2]) +"\r\n"
outputf.write(line)
for row in past_file_contents:
if row[1] in proposed_customer_name:
continue
else:
line = str(row[0]) + ", " + str(row[1]) + ", " + str(row[2]) + "\r\n"
outputf.write(line)
print("Files merged successfully!")
# reads the file and returns the content as 2D lists
def load_file(path):
file_contents = []
with open(path, 'r') as pastf:
for line in pastf:
cells = line.split(",")
row = []
for cell in cells:
if(cell.lower().strip()=="customer number"):
break
else:
row.append(cell.strip())
if len(row)>0:
file_contents.append(row)
return file_contents
past_file_path="F:\\Past Customer.txt"
proposed_file_path="F:\\Proposed Customer.txt"
merged_file_path="F:\\Merged File.txt"
merge_file(past_file_path,proposed_file_path,merged_file_path)
