Python int函数

int(x, base=10)

# 将字符串转换为整数
num_str = "123"
num_int = int(num_str)
print(num_int)

# 将浮点数转换为整数
num_float = 3.14
num_int = int(num_float)
print(num_int)

# 将二进制字符串转换为十进制整数
binary_str = "1010"
decimal_int = int(binary_str, 2)
print(decimal_int)

# 将十六进制字符串转换为十进制整数
hex_str = "1A"
decimal_int = int(hex_str, 16)
print(decimal_int)

# 错误处理示例
try:
    num_str = "abc"
    num_int = int(num_str)
    print(num_int)
except ValueError:
    print("无法将字符串转换为整数")
