1. Description
| name | meaning |
|---|---|
| tpye() | The return type of the variable |
| dtpye | Returns the type of data in the array |
| astype() | Change the type of data |
2. The code portion
2.1 type()
import numpy as np
base_data = [1,3,4]
print(type(base_data))
Print results, variable "List" type
2.2 dtype
mod_data = np.array(base_data) # 列表转成数组
print(type(mod_data))
print(mod_data.dtype)
Print result, the variable is an array type; array data type int32
2.3 astype()
Converting the int32 into float32
2.3.1 a first conversion method
mod_float_data = mod_data.astype("float32")
2.3.2 The second conversion method
mod_float_data = mod_data.astype(np.float32)
2.3.3 Test Type
print(type(mod_float_data))
print(mod_float_data.dtype)
Print the results can be seen that variable is an array type, the data type is an array float32
