如何在多个行打印输出

Question

var1 = "arun"
var2 = "86"
var3 = 4
var4 = 29
print(100*(var1+var2))

在上面的python代码中，我得到的是单行输出输出

我想把它打印成多行。我该怎么做才能成功呢?我已经尝试使用n转义字符，但我没有得到所需的输出。

Answer 1

如果你的意图是打印相同的东西100次，我建议使用for循环而不是字符串乘法;它将消耗更少的内存(并不是说6个字符字符串的100倍很多，但如果数字更大，它可能会变得很重要)，并且它使意图对普通读者更明显:

var1 = "arun"
var2 = "86"
for _ in range(100):
print(var1+var2)

如果你真的想构造一个带有换行符的字符串，除了在乘法之前插入n:

print(100*(var1+var2+'n'))

另一个选择是使用str.join和列表乘法:

print('n'.join([var1+var2]*100))

或生成器表达式:

print('n'.join(var1+var2 for _ in range(100)))

或使用print()中的sep参数执行上述任一操作:

print(*(var1+var2 for _ in range(100)), sep='n')

Answer 2

添加n字符:

var1 = "arun"
var2 = "86"
var3 = 4
var4 = 29
print(100*(var1+var2+'n'))

Answer 3

根据您提到的代码，输出如下:

arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86arun86

根据我对问题的理解，期望的输出如下:

要获得上述输出，请使用"n"在您的代码中，如下所示:

var1 = "arun"
var2 = "86"
var3 = 4
var4 = 29
print(100*(var1+var2+'n'))

还有，如果你需要"86"同样要在下一行打印，您可以使用下面的代码等等:

var1 = "arun"
var2 = "86"
var3 = 4
var4 = 29
print(100*(var1+"n"+var2+'n')) 

并期望以下输出:
