How to convert a list to a string in Python
Use ''.join(lst) if the elements are strings. For other types, wrap with map(str, ...).
words = ["hello", "world", "python"]
result = " ".join(words)
print(result) # 'hello world python'str.join(iterable) is the idiomatic way. The string you call it on is the separator — ' '.join for spaces, ','.join for CSV-style, ''.join for no separator at all.
Every element in the iterable must already be a string. If you have numbers or other types, map them through str first: ', '.join(str(n) for n in [1, 2, 3]). Trying to join a list containing an int raises TypeError.
Do NOT use str(lst) — that produces the Python repr with square brackets and quotes ('[1, 2, 3]'), which is rarely what you want. It's fine for debug printing but not for building output text.
Variations
Join numbers
nums = [1, 2, 3]
print(", ".join(str(n) for n in nums)) # '1, 2, 3'Generator expression is enough — no need to build an intermediate list.
Just get repr(list)
nums = [1, 2, 3]
print(str(nums)) # '[1, 2, 3]'For debug only — keeps the brackets and commas.
Join with a newline (multi-line)
lines = ["first", "second", "third"]
print("\n".join(lines))Common for building console output or file contents.
