# 将字符串转换为整数
string_number = "123"
integer_number = int(string_number)
print(integer_number)  # 输出: 123

# 将浮点数转换为整数（会舍弃小数部分）
float_number = 123.456
integer_number = int(float_number)
print(integer_number)  # 输出: 123

# 带基数的转换，例如将二进制、八进制、十六进制字符串转换为整数
binary_number = "1010"
integer_number = int(binary_number, 2)
print(integer_number)  # 输出: 10

octal_number = "17"
integer_number = int(octal_number, 8)
print(integer_number)  # 输出: 15

hexadecimal_number = "1a"
integer_number = int(hexadecimal_number, 16)
print(integer_number)  # 输出: 26

int() 函数在 Python 中用于将其他类型的值转换为整数。它可以接受一个字符串或浮点数作为参数，并返回相应的整数值。此外，int() 还可以接受第二个参数来指定字符串的基数（例如二进制、八进制、十六进制等）。
