IndentationError: expected an indented block

Question

Can someone please tell me what I’m doing wrong in this Python code sample?

for i in range(len(Adapters)):
print Adapters[i]

I’m trying to list/print out the Array content but the code gives me error on print command: IndentationError: expected an indented block

Answer 1

You need to indent inside the for loop block

for i in range(len(Adapters)):
    print(Adapters[i])

A better way would be:

for item in Adapters:
    print(item)

Answer 2

You need to indent the print statement inside the body of the for-loop

for i in range(len(Adapters)):
    print Adapters[i]

If you want to streamline your code, the 2nd loop suggested by @jamylak is the way to go.

Answer 3

When you have a block that starts with a phrase that ends in a colon, you need to indent the next lines until you are done. This goes for loops, if statements, etc.

if 0!=-1:
    print "Good!"

while 0!=-1:
    print "BWAHAHAHA"

for i in range(1,100):
    print i

try:
    print blah
except NameError:
    print "Blah is not defined"

Answer 4

As your error says you are missing an indentation on the second line. Unlike other languages like Java, Python uses indentation to determine the grouping of the statements.
It should be:

for i in range(len(Adapters)):
    print Adapters[i]
