How to solve IndexError: Replacement index 1 out of range for positional args tuple format()
IndexError: Replacement index 1 out of range for positional args tupleappears when the placeholders are more than arguments.
Let's see an example.
lang = "python"
print("{} {}".format(lang))
Output:
Traceback (most recent call last): File "test.py", line 15, in <module> print("{} {}".format(lang)) IndexError: Replacement index 1 out of range for positional args tuple
As you can see, we've 2 placeholders {} and one format argument.
So how to solve this issue:
Solution 1: add the argument or delete the placeholder
add the argument:
lang = "python"
fram = "django"
print("{} {}".format(lang, fram))
Output:
python django
delete the placeholder:
lang = "python"
print("{}".format(lang))
Output:
python
Solution 2: Same value in all placeholders
If you want to insert the same value for all placeholders, follow this code:
lang = "python"
print("{0} {0}".format(lang))
Output:
python python
