Python使用type代替cat

def cat(filename):
    try:
        with open(filename, 'r') as file:
            content = file.read()
            print(content)
    except FileNotFoundError:
        print("File not found.")

# 使用type函数代替cat命令
def cat_type(filename):
    try:
        with open(filename, 'r') as file:
            content = type(file)
            print(content)
    except FileNotFoundError:
        print("File not found.")

# 调用cat函数
cat('example.txt')

# 调用cat_type函数
cat_type('example.txt')
