Eliminating Newline Characters from readlines()
When working with text files, it's often necessary to extract line-by-line data into a list. However, using the readlines() method can introduce unwanted newline characters ("n") at the end of each line.
Problem:
A text file contains values separated by line breaks, as follows:
Value1 Value2 Value3 Value4
The goal is to store these values in a list, but readlines() returns a list with newline characters appended to each value:
['Value1\n', 'Value2\n', ...],
Solution:
To remove the newline characters, use the splitlines() method instead of readlines():
with open(filename) as f: mylist = f.read().splitlines()
This approach reads the entire file contents into a string and then splits it into lines using the splitlines() method, which returns a list without newline characters.
