python中print后面加逗号

python中print输出一行，如果想多次输出的内容不换行，可以在print后面加逗号

例如

每个输出一行

phrase = "abcdefg"

# Add your for loop

for char in phrase:

        print char

a

b

c

d

e

f

g

 

输出在同一行

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 . . .
