Problem with for-loop in python

help you fix your problem The key-extractor Alex mentions is trivial enough to put in a lambda function
>>> array = ['ca', 'bd', 'ac', 'ab']
>>> order = ['a', 'b', 'c', 'd']
>>> sorted(array, key=lambda v:map(order.index,v))
['ab', 'ac', 'bd', 'ca']

>>> order = ['b', 'a', 'c', 'd']
>>> sorted(array, key=lambda v:map(order.index,v))
['bd', 'ab', 'ac', 'ca']

>>> order = ['d', 'c', 'b', 'a']
>>> sorted(array, key=lambda v:map(order.index,v))
['ca', 'bd', 'ac', 'ab']
>>> order = ['a', 'b', 'c', 'd']
>>> map(order.index,array[0])
[2, 0]
>>> map(order.index,array[1])
[1, 3]
>>> map(order.index,array[2])
[0, 2]
>>> map(order.index,array[3])
[0, 1]

For Loop problem in Python

wish of those help I think this is because you are not resetting start_position; variables in Python are scoped to their enclosing function or class or module, but not to their enclosing loop. So try adding this line:
for x in authorList:
    start_position = 0   # Add this
    while True:

While Loop Breaking Problem (Python)

it helps some times I am currently trying to connect to a GPS Bluetooth device. My Python 2.7 code worked correctly initially but I have now tried to implement my code into a while loop so that, whilst my device is not available, it will continue to keep on looping for it. Unfortunately, my code seems to be stuck in a loop and repeatedly prints out the error message "Unable to Locate Bluetooth GPS Device. Retrying..." I'm using the Bluetooth module from PyBluez. , The line
discovered_devices = discover_devices()
else:
    continue
break

should help you out the problem is that you put Loop (note Capital L) and then loop (note not Capital l) this should work:

i have a problem with strings and for loop in python

Does that help I assume you are quite new to programing, so use a the following for loop:
name = "mohammadhosein"
output = ''
for i, c in enumerate(name):
    if i % 2 == 0:
        output += c.upper()
    else:
        output += c

# output will be 'MoHaMmAdHoSeIn'
>>> ''.join([c.upper() if i % 2 == 0 else c for i, c in enumerate(name)])
'MoHaMmAdHoSeIn'
for index in range(0, len(name)):
    if(index % 2 == 0):
        print(name[index].upper(), end='') # use upper instead of title it is more readable
    else:
        print(name[index], end='')
print()
