I have the following string in python:
'this is my string (x,x,x,x)'
I want to replace each x per each number in this list:
[1,2,3,4]
So, the final output should be this:
'this is my string (1,2,3,4)'
I have tried to solve it with different approaches but I can't do it.
I don't know if there is an efficient way to do this.
What about this one?
'this is my string (x,x,x,x)'.replace('x','{}').format(*[1,2,3,4])
'this is my string (x,x,x,x)'.replace('x','{}').format(*[1,2,3,4]) ?here the solution
s = 'this is my string (x,x,x,x)'
s
'this is my string (x,x,x,x)'
for i in range(1, len(s.split('x'))):
s = s.replace('x', str(i), 1)
s
'this is my string (1,2,3,4)'
to prevent malcontent
you can use
s.count('x,') + 1 instead of len(s.split('x'))
if you have x in your string
len(s.split('x')) -> s.count('x') ??s.count('x,') -- the last x does not have a comma afterwards.
[1,2,3,4] ? please, bear in mind, that the numbers are just a place holders, the actual values can be different.
