python int, float, complex, bool, None, bytes, str, tuple的定义方法

# 定义int类型数据
int_num = 1
print(int_num, type(int_num))
int_num = int(1)
print(int_num, type(int_num))

# 定义float类型数据
float_number = 1.1
print(float_number, type(float_number))
float_number = float(1.1)
print(float_number, type(float_number))

# 定义complex类型数据
complex_number = 1+2j
print(complex_number, type(complex_number))
complex_number = complex(2, 1)
print(complex_number, type(complex_number))

# 定义bool类型的数据
bool_number = True
print(bool_number, type(bool_number))
# 不写默认false
bool_number = bool()
print(bool_number, type(bool_number))

# 定义None类型的数据
none_nub = None
print(none_nub, type(none_nub))

# 定义字节类型的数据
bytes_number = b"nihao"
print(bytes_number, type(bytes_number))
bytes_number = bytes(1)
print(bytes_number, type(bytes_number))

# 定义字符串类型数据
str_data = "Python"
print(str_data, type(str_data))
str_data = str("Python")
print(str_data, type(str_data))

# 定义元组类型数据
tuple_data = (1, 2, 3)
print(tuple_data, type(tuple_data))
