一般来说, 一行就是一条语句, 但有时语句过长不利于阅读, 一般会写成多行的形式, 这时需要在换行时使用反斜杠: \
name = "Lilei" age = 23 gender = "boy" str = "Hello, my name is " + \ name + \ ". I'm " + \ str(age) + \ "years old " + \ gender print(str) # Hello, my name is Lilei. I'm 23years old boy
如果语句换行时包裹在中括号: [], 大括号: {}, 或者括号: (), 中, 则不必反斜杠换行, 如下:
name = "Lilei" age = 23 gender = "boy" str = ("Hello, my name is " + name + ". I'm " + str(age) + "years old " + gender) print(str)
