遍历字符串的字符

Question

I have a string which I need to do a certain operation on

string="_,_,_,56"

When I iterate through the elements of the string I am getting an output as

_
,
_
,
_
,
2
4

I want the output as :

_ _ _ 56

That means I do not want ',' to be considered as a character and I want the two-digit number to be considered as a single character.

Is it possible to achieve?

Answer 1

Do this:

string = "_,_,_,56"
new_string = string.split(",")
print(new_string)
# ['_', '_', '_', '56']

The str.split() method allows you to split a single string into a list of strings, using the given character as a separator.

Answer 2

Two Three simple ways using str methods join , split and replace :

>>> string="_,_,_,56"
>>> print(string.replace(',', ' '))
_ _ _ 56
>>> print(' '.join(string.split(',')))
_ _ _ 56

Another version thanks to @Blckknght is using the * operator to unpack the split ted list:

>>> print(*string.split(','))
_ _ _ 56
