difference: repr(a) and str(a)

[jenya56]

In my program, I have value a=0.24
when I say : str(a) it prints 0.24
when I say: repr(a) ir print '0.24'
Why does str(a) not work? Thanks

In [1]: a=0.24

In [2]: str(a)
Out[2]: '0.24'

In [3]: repr(a)
Out[3]: '0.23999999999999999'

In [4]: print str(a)
------> print(str(a))
0.24

So it probably is working, depending whether or not you used the print command (which drops the quotes from a string).

See the Python documentation for an explanation of str() and repr(). From the docs:
"Many values, such as numbers or structures like lists and dictionaries, have the same representation using either function. Strings and floating point numbers, in particular, have two distinct representations ."
