create loop with parsing in python

To create a loop with parsing in Python, you can use the while loop or the for loop.

Here is an example of using a for loop to iterate over a collection of data that needs to be parsed:

main.py
data = ['1,John,Doe', '2,Jane,Smith', '3,Bob,Johnson']

for item in data:
    parsed_item = item.split(',')
    id = parsed_item[0]
    first_name = parsed_item[1]
    last_name = parsed_item[2]
    # do something with the parsed data
    print(id, first_name, last_name)
272 chars
10 lines

In this example, the data list contains strings that need to be parsed by splitting them based on the comma delimiter. The for loop iterates over each item in the list and parses it using the split() method. The parsed data is then assigned to individual variables that can be used for further processing.

Alternatively, you can also use the while loop to read and parse data from a file line by line:

main.py
file = open('data.txt', 'r')
line = file.readline()

while line:
    parsed_line = line.strip().split(',')
    id = parsed_line[0]
    first_name = parsed_line[1]
    last_name = parsed_line[2]
    # do something with the parsed data
    print(id, first_name, last_name)
    line = file.readline()

file.close()
312 chars
14 lines

In this example, the file object is opened in read mode and the readline() method is used to read the file line by line until the end of the file is reached (line returns an empty string). Each line of data is then parsed using the split() method, and the resulting data is assigned to individual variables. Finally, the parsed data is printed to the console, and the readline() method is called again to read the next line of data.
