Pythonで「大文字と小文字を変換する(lower, upper, capitalize, title, swapcase)」の動作を確認してみました。以下のページを参考にしました。

print("Hello".lower())
print("APPLE".lower())

print("Hello".upper())
print("apple".upper())
print("Hello".upper())
print("apple".upper())

print("hello python".capitalize())
print("MY FAVORITE THINGS".capitalize())
print("hello python".capitalize())
print("MY FAVORITE THINGS".capitalize())

print("hello python".title())
print("MY FAVORITE THINGS".title())
print("hello python".title())
print("MY FAVORITE THINGS".title())

print("Hello".swapcase())
print("apple".swapcase())
print("Hello".swapcase())
print("apple".swapcase())

以下のコマンドを実行しました。

$ python3 sample.py
