リストの要素を横並びで出力する

Last updated at Posted at 2021-08-22

"".join()の使い方

"要素の間に入れる文字".join(リスト)
※リストの要素がint型だと使えない

.py
l = ["a", "b", "c", "d"]
print(",".join(l))
# a,b,c,d
print("".join(l))
# abcd
print(" ".join(l))
# a b c d

リストの要素がint型の場合

str型に変換してから"".join()を使う

.py
l = [1, 2, 3, 4]
l = [str(x) for x in l]
print(" ".join(l))
# 1 2 3 4
