python中print后面加逗號

python中print輸出一行，如果想多次輸出的內容不換行，可以在print后面加逗號

例如

每個輸出一行

phrase = "abcdefg"
# Add your for loop
for char in phrase:
        print char

a
b
c
d
e
f
g

 

輸出在同一行

phrase = "A bird in the hand..."

# Add your for loop
for char in phrase:
    if(char == "A" or char == 'a'):
        print 'X',
    else:
        print char,
#Don't delete this print statement!
print

X   b i r d   i n   t h e   h X n d . . .
