如何从多个文本文件或 csv 文件中读取数据并创建 output 文件

Question

I am new to Python. My requirement is:

File A (text file): 240 241 and so on

File B (text file): 250 251 and so on

Want to write a script which will take 1 record at a time from each file above and give output as:

Insert into Table A Where Num1 = 1st record from file A and Num2 = 1st record from file B Update Table A Where Num1 = 1st record from file A and Num2 = 1st record from file B

Insert into Table A Where Num1 = 2nd record from file A and Num2 = 2nd record from file B Update Table A Where Num1 = 2nd record from file A and Num2 = 2nd record from file B

Thought of making writing the static (Insert into Table A Where Num1) in file c and use it as below while writing final output file:

for open('output.txt','w') as f: f.write(data from filec + looping data from file A)

Can someone provide solution how can I get outfile data?

Answer 1

if the file is a text file, then you need the open two files and loop on their lines (I don't recommend using with open ("file.txt") as t when dealing with multiple files at once, so if the records are on separate lines you just need:

file1 = open("file1.txt")
file2 = open("file2.txt")

for lineOf1, lineOf2 in zip(file1, file2):

and here lineOf1 and lineOf2 are the records you need

and if the records are not on separate lines just add: lineOf1.split("the character separates the records on each line") and you will have a list of records so you can loop on it again

but if you are dealing with csv I recommend having a look at pandas library.
