Whitespace python for loop - for when you don't want to use split( )

gistfile1.py

entry = input("Enter a Mayan date: ")

i=0 # this is used to track our position in the string
output = "" # start with output set to nothing
while entry[i:]:

    # if we hit a space, then we've got to the end of that number
    # print it out and reset the output
    if entry[i] == " ":
        print (output)
        output = ""

    # otherwise, append to the output string
    else:
        output += entry[i]

    # increment position
    i+=1

# print the last number as there isn't a space after it
print(output)


##############

# easier way is to use split!
str = "3 52 9 54 67"
strList = str.split( ) # note the space between the brackets

print ('baktun ', strList[0])
print ('katun  ', strList[1])
print ('tun    ', strList[2])
print ('uinal  ', strList[3])
print ('kin    ', strList[4])

# or another way
# using a while loop for each part

entry = input("Enter a Mayan date: ")
baktun = ""
katun = ""
tun = ""
uinal = ""
kin = ""

i = 0 # our position tracker

# we pop out the loop when we find a space
while entry[i] != " ":
    # print('debug baktun ', entry[i]) #uncomment these lines to see debug info. very useful
    baktun += entry[i]
    i += 1
    
print (baktun)
i += 1 # moving along the array to make sure we're not on a space for the next comparison

# we still want to look for a space
while entry[i] != " ":
    # print('debug katun ', entry[i])
    katun += entry[i]
    i += 1

print (katun)
i += 1 # make sure we keep moving along the array after every loop

while entry[i] != " ":
    # print('debug tun ', entry[i])
    tun += entry[i]
    i += 1

print (tun)
i += 1 # still moving ;)

while entry[i] != " ":
    # print('debug uinal ', entry[i])
    uinal += entry[i]
    i += 1

print (uinal)
i += 1

# we're not looking for a space here, we just want whatever is remaining
# this is the only time we use the colon :
while entry[i:]:
    # print('debug kin ', entry[i])
    kin += entry[i]
    i += 1

print (kin)
