Python for Data Science, AI & Development - Week 4 Hands-On Lab: Writing Files with Open

PY0101EN-4-2-WriteFile.ipynb

Notes:

• members = memList.readlines() will read all (remaining) lines in file.
• inactive.write(members.pop(members.index(member))) would remove the current member from the list, members, and append it to the file, inactive, but this will only work if we are manually indexing through members, i.e. not using e.g. "for member in members".
• If we expect fewer members to fall into "inactive" category than "active", more efficient to collect inactive members.
• In that case, the final write loop decides where to write by checking whether the member is in the "inactive" collection.
