✅ Q&A: Can We Use `join(line)` Without `”;”` in Python?

[Rajeev Bagra]

Q1) Can I write join(line) directly in Python?

❌ Answer: No.
join() is not a standalone function like len() or print().

✅ It is a string method, so it must be called like this:

"separator".join(list_items)

---

Q2) Why do we write ";".join(line) instead of join(line)?

✅ Answer:
Because Python needs to know what separator to place between each element of the list.

Example:

";".join(["Amit", "98765", "12345"])

Output:

Amit;98765;12345

---

Q3) If I don’t want ;, how can I join without it?

✅ Answer:
Use an empty string "" as the separator:

"".join(line)

Example:

line = ["Amit", "98765", "12345"]
print("".join(line))

Output:

Amit9876512345

---

Q4) What happens if I use "" as the separator?

✅ Answer:
All items get joined without any gap, which can make the output harder to read.

Example:

"".join(["Rajeev", "99999"])

Output:

Rajeev99999

---

Q5) Can I join using something else besides ;?

✅ Answer: Yes ✅ You can use any separator you want, like:

• Space:

" ".join(line)

• Comma:

",".join(line)

• Dash:

" - ".join(line)

---

✅ Final Summary:
You must write "something".join(line) — and if you want no separator, use:

"".join(line)
