Why is that Python always prints an extra newline when I run the code below? I tried to re-write the code to eliminate any unintended blank space but it still prints out an extra new line. Anyone knows why? Thanks.
def main():
names_in() #This function import the file and read all the content and put the content into a list.
print_names(names_in) # Before the names are sorted.
def names_in():
infile = open('names.txt','r')
names_list = [] #empty list.
names = infile.readline() # read contents.
#loop for continue to read.
while names != '':
names = infile.readline() #continue to the next name.
names = names.rstrip('\n') #return a copy of the string which all \n has been stripped from the end of the string.
names_list.append(names) #write names in the file into a list.
infile.close()
return names_list #return the list back to the function.
def print_names(names_in): #This function will print out the names in the list one per line, single-spaced.
for item in names_in():
print(item)
main()
