how to print out a string and list in one line-python

问题

a=[1,2,3]
print "the list is ：%"%(a)

I want to print out one line like this: the list is：[1,2,3] I can not make it within one line and I have to do in this way:

print " the list is :%"
print a

I am wondering whether I can print out something that combine with string formatting and a list in ONE line.

回答1:

The simplest way is what CodeHard_or_HardCode said in the comments. For Python 3 it would be:

a=[1,2,3]
print('This is a list', a)

This is a list [1, 2, 3]

回答2:

I suggest using the string format method, as it is recommended over the old % syntax.

print("the list is: {}".format(a))

回答3:

At least in Python 2.7.4., this will work:

print " the list is " + str(a)

回答4:

Try this:

a = [1,2,3]
print("the list is: %s" % a)

回答5:

print(f"the list is: {[1,2,3]}")

you will need to use python 3.7.1 or higher I believe, as this is when they added string interpolation
