              深入Python字符串【每日一個知識點第138期-Python】

              字符串是一種基本的數據類型,也是最常用的數據類型。掌握字符串的各種操作方式,不僅有助于我們深入了解編程語言的內部機制,也對于效率提高有不可估量的作用,今天我們就帶大家來深入了解一下字符串。


              字符串是 Python 中最常用的數據類型。我們可以使用引號(‘或”)來創建字符串。

              創建字符串很簡單,只要為變量分配一個值即可。例如:

              var1 = Hello World! var2 = Runoob

              Python 訪問字符串中的值

              Python 不支持單字符類型,單字符在 Python 中也是作為一個字符串使用。

              Python 訪問子字符串,可以使用方括號來截取字符串,如下實例:

              實例(Python 3.0+)

              #!/usr/bin/python3 var1 = Hello World! var2 = Runoob print (var1[0]: , var1[0]) print (var2[1:5]: , var2[1:5])

              以上實例執行結果:

              var1[0]:  H
              var2[1:5]:  unoo
