How to correct the Invalidsyntax Error in line 7?

Question

I have a list and want to input a digit so that the output is the list's element on the respective position.
The variable "word" is supposed to be that digit representing the position, starting from 1 up to len(list).
Why is there an InvalidSyntaxError in line 7?

1 command=input()
2 word=input()
3 if command=='pos':
4 if word.isdigit():
5 if 1<=int(word)<=len(list):
6 print('element on position',str(word),+':'+str(list(word-1))
7 else:
8 print('Position',word,'out of range.')
9 else:
10 print('Error: Enter digit.')

Thank You in advance!

Answer 1

There is a missing closing bracket at line 7

Answer 2

...and a comma in b/w str(word) and ':' (line 6)
