I have an array on hand. Now I'd like to have a combined print of text and array entries, so I'd use .format.
I'd like to now if there is a way to get the following work with that for loop (not a[0],a[1],a[2]).
a = [1,2,3]
print("""
A is {}
B is {}
C is {}
""".format(i for i in a))
This one returns IndexError: tuple index out of range
Use the * to unpack the arguments as an argument list:
a = [1,2,3]
print("""
A is {}
B is {}
C is {}
""".format(*[i for i in a]))
Or even better, if you’re not dependent on the individual contents of the list;
a = [1,2,3]
print("""
A is {}
B is {}
C is {}
""".format(*a))
Python reads both of these identically: *a is unpacked as an argument list. You can do something similar with dictionaries (using a double ** which unpacks keyword arguments):
a = {"alpha": 1, "beta": 2, "gamma":3}
print("""
A is {alpha}
B is {beta}
C is {gamma}
""".format(**a))
