Answer 1

using f- string should be the preferred way to make formatted output.

# >>> there is no need to use multiple f-strings, as you can can use {multiple expressions} in one f-string
nums=[4,5,6]
msg= f"Numbers: {nums[0]}{nums[1]}{nums[2]}"
print(msg)

# or do it this way:
print(f"Numbers: {nums[0]}{nums[1]}{nums[2]}")

# or with basic print and unpack operator
print('Numbers: ',*nums,sep='')

Adding onto what Md. Nasif-ur-Rahman Rimon, I’ve updated my answer with a more compact way of doing it with the splat operator.
Refer to my previous answer.

Adding onto what Md. Nasif-ur-Rahman Rimon, you should change line 4 to:
msg = msg.format(nums[0], nums[1], nums[2])

EDIT:
Or, to simplify:
msg = msg.format(*nums)
Using *nums is the splat operator, similar to the JS spread operator..

Answer 9

nums=[4,5,6]

msg_1= f"Numbers {nums[0]} {nums[1]} {nums[2]}"

msg_2 ="Numbers {} {} {}".format(*nums)

msg_3 = "Numbers %i %i %i" %(nums[0],nums[1],nums[2])

print(msg_1)
print(msg_2)
print(msg_3)

Answer 11

# you are repeating your code.
# try this code.

nums = [4,5,6]
print(f"Numbers: {nums[0] + nums[1] + nums[2]}")
print(f"Numbers: {nums[0]}, {nums[1]}, {nums[2]}")

Answer 12

Line 2
Not :(semicolon) that is =
Line 4:
format function not come in next line. That come in end of line 4. There not is =, {} that is () and beginning with .(dot) at end of line 3.

msg = 'Number:{0},{1},{2}'.format(nums[0],nums[1],nums[2])
