Read And Append The Specific Content
Subsequent to my previous question what if I want to append line. In that case others block are also specified in output file. Input file file1.txt ##### Xyz * [] Task 112 * [] Cl
Solution 1:
Read all lines from the input file but write only those that start with specified strings:
with open("file1.txt", "rt") as finp:
with open("file2.txt", "wt") as fout:
for line in finp.readlines():
if line.startswith("#####") or line.startswith("* [x]"):
fout.write(line)
