              Python數據類型之數據類型轉換【每日一個知識點第121期-Python】

              對于一個程序員來講,數據類型的重要性無需多言。在Python3中,有多達六種數據類型,各類型均有自己獨特的屬性和操作方式。今天我們首帶大家來了解一下Python3的數據類型的轉換。


              有時候,我們需要對數據內置的類型進行轉換,數據類型的轉換,你只需要將數據類型作為函數名即可。

              以下幾個內置的函數可以執行數據類型之間的轉換。這些函數返回一個新的對象,表示轉換的值。

              函數 描述
              int(x [,base]) 將x轉換為一個整數
              float(x) 將x轉換到一個浮點數
              complex(real [,imag]) 創建一個復數
              str(x) 將對象 x 轉換為字符串
              repr(x) 將對象 x 轉換為表達式字符串
              eval(str) 用來計算在字符串中的有效Python表達式,并返回一個對象
              tuple(s) 將序列 s 轉換為一個元組
              list(s) 將序列 s 轉換為一個列表
              set(s) 轉換為可變集合
              dict(d) 創建一個字典。d 必須是一個序列 (key,value)元組。
              frozenset(s) 轉換為不可變集合
              chr(x) 將一個整數轉換為一個字符
              ord(x) 將一個字符轉換為它的整數值
              hex(x) 將一個整數轉換為一個十六進制字符串
              oct(x) 將一個整數轉換為一個八進制字符串
