Consider the code:
firstName = raw_input("Your fist Name: ")
lastName = raw_input("Your last Name: ")
print "Hello %s, May I call you" \
"Mr. %s?" % (firstName,lastName)
In line 3, what is the use of \\
?
它允许您进行换行并在下一行继续您的语句
The \\
tells Python that the statement continues on the next line. So, the print
statement doesn't end on the first line, it continues on the next.
print "Hello %s, May I call you" \
"Mr. %s?" % (firstName,lastName)
Is the same as:
print "Hello %s, May I call youMr. %s?" % (firstName,lastName)
The \\
character is used to break up long lines so they're easier to read and manage. The third and fourth lines could have been written as a single line without the \\
instead:
print "Hello %s, May I call youMr. %s?" % (firstName,lastName)
(note there is no space between "you" and "Mr." in the original post either)
使您能够将一行字符串溢出到多行。
