笨方法学python--打印

1 print 语句 尾端的逗号

end1 = "C"
end2 = "h"
end3 = "e"
end4 = "e"
end5 = "s"
end6 = "e"
end7 = "B"
end8 = "u"
end9 = "r"
end10 = "g"
end11 = "e"
end12 = "r"

# watch that comma at the end.  try removing it to see what happens
print end1 + end2 + end3 + end4 + end5 + end6,
print end7 + end8 + end9 + end10 + end11 + end12

结果：
Cheese Burger

若没有逗号
Cheese
Burger

2 3个双引号的使用
引号之间不能有空格
