Python 3 Simon说For Loop字符串比较

str1 = "hello"
str2 = "world"

if len(str1) == len(str2):
    for i in range(len(str1)):
        if str1[i] != str2[i]:
            print("字符串不相等")
            break
    else:  # 注意这里的else是与for循环关联的，不是if
        print("字符串相等")
else:
    print("字符串长度不同，因此不相等")

text = "hello world"
vowels = "aeiou"

for char in text:
    if char in vowels:
        print(f"{char} 是元音字母")

original = "hello world"
converted = ""

for char in original:
    if char.islower():
        converted += char.upper()
    else:
        converted += char.lower()

print(converted)  # 输出 "HELLO WORLD"

str1 = "你好"
str2 = "你好"

# 确保字符编码一致
if str1.encode('utf-8') == str2.encode('utf-8'):
    print("字符串相等")
else:
    print("字符串不相等")
