1、方法说明
如果只是想把Python的对象转换成文字串的话，str()函数是回到人类可读值的表示。
2、语法
class str(object='')
3、实例
>>> s = 'Hello, world.'
>>> str(s)
'Hello, world.'
>>> repr(s)
"'Hello, world.'"
>>> str(1/7)
'0.14285714285714285'
>>> x = 10 * 3.25
>>> y = 200 * 200
>>> s = 'The value of x is ' + repr(x) + ', and y is ' + repr(y) + '...'
>>> print(s)
The value of x is 32.5, and y is 40000...
>>> # The repr() of a string adds string quotes and backslashes:
... hello = 'hello, worldn'
>>> hellos = repr(hello)
>>> print(hellos)
'hello, worldn'
>>> # The argument to repr() may be any Python object:
... repr((x, y, ('spam', 'eggs')))
"(32.5, 40000, ('spam', 'eggs'))"
以上就是python中str()函数转换字符串的方法，希望对大家有所帮助。更多Python学习指路：python基础教程
