在 Python 中返回標量資料型別的字串表示法
要返回標量資料型別的字串表示法,可用 Python Numpy 中的 sctype2char() 方法。第一個引數(標量資料型別時),返回相應的字串字元。如果是一個物件,sctype2char 會嘗試推斷它的標量型別,然後返回相應的字串字元。
步驟
首先,匯入所需的庫——
import numpy as np
一個標量型別的字串表示法——
for i in [np.int32, np.double, np.complex_, np.string_, np.ndarray]: print(np.sctype2char(i))
返回 int 資料型別的字串表示法——
print("\nThe string representation of int types...")
for j in [np.int16, np.int32,np.int64]:
print(np.sctype2char(j))返回 float 資料型別的字串表示法——
print("\nThe string representation of float types...")
for j in [np.float16, np.float32,np.float64]:
print(np.sctype2char(j))示例
import numpy as np
# To return the string representation of a scalar dtype, use the sctype2char() method in Python Numpy
# The 1st argument, if a scalar dtype, the corresponding string character is returned.
# If an object, sctype2char tries to infer its scalar type and then return the corresponding string character.
print("The string representation of a scalar type...")
for i in [np.int32, np.double, np.complex_, np.string_, np.ndarray]:
print(np.sctype2char(i))
# Return the string representation of int types
print("\nThe string representation of int types...")
for j in [np.int16, np.int32,np.int64]:
print(np.sctype2char(j))
# Return the string representation of float types
print("\nThe string representation of float types...")
for j in [np.float16, np.float32,np.float64]:
print(np.sctype2char(j))輸出
The string representation of a scalar type... i d D S O The string representation of int types... h i l The string representation of float types... e f d
