Objective
I have a string variable:
use_this_string = "If you want to <something here>, then first learn it"
and I want to insert a user input value into it like (in REPL mode):
>>> placeholder_value = input("What do you want to do: ")
What do you want to do: swim
and when the code is executed, the place_holder in use_this_string should be replaced with the value of placeholder_value variable.
Pseudo code for this would be like
use_this_string = "If you want to <something here>, then first learn it"
placeholder_value = input("What do you want to do: ")
# Not real code
print(use_this_string.insert(placeholder_value))
# place the inputed value into the string into placeholder position
expected output:
What do you want to do: swinm
If you want to swim, then first learn it
What I thought of
I've thought including s placeholder string in the variable like
# literally the code
use_this_string = "If you want to <placeholder>, then first learn it"
placeholder_value = input("What do you want to do: ")
print(use_this_string.replace('<placeholder>', placeholder_value)
However, I had this question for a long time, I want to use a solution often. In case the string already contained the substring <placeholder>, then it would be replaced as well. Any other solutions..? TIA
