如何将每个输出打印到文件中

Question

我不太清楚如何将输出打印到文件中。

样品输入

0 
2 
1 
3 
5 

样品输入

S 
SLSLSRS 
SLS 
SLSLSRSLSLSRSRS 
SLSLSRSLSLSRSRSLSLSLSRSRSLSRSRSLSLSLSRSLSLSRSRSRSLSLSRSRSLSRSRS 

这里dragon.dat的内容是我的代码：

infile = open("dragon.dat", "w") 
def B(n): 
    if n>22: 
     return "Enter integer less than 22" 

    elif n==0: 
     return "S" 
    str=B(n-1) 
    reversestr=str 
    str +="L" 
    reversestr=reversestr.replace("L","T") 
    reversestr=reversestr.replace("R","L").replace("T","R") 
    reversestr=reversestr[::-1] 
    return str + reversestr 

print(B(0)) # these input will be printed in the python shell 
print(B(2)) 
print(B(1)) 
print(B(3)) 
print(B(5)) 

infile.write(B(0)) 
infile.write(B(2)) 
infile.write(B(1)) 
infile.write(B(3)) 
infile.write(B(5)) 


infile.close() 

我的输出中的文件：

SSLSLSRSSLSSLSLSRSLSLSRSRSSLSLSRSLSLSRSRSLSLSLSRSRSLSRSRSLSLSLSRSLSLSRSRSRSLSLSRSRSLSRSRS 

我怎样才能将它们分成每一行就像样本输出？

Answer 1

写作时，您错过了\n。改为使用infile.write(B(i) + '\n')。

Answer 2

infile.write("\n".join([B(i) for i in range(6)]) 

Answer 3

使用打印：print(B(1), file=infile)或

print(*[B(i) for i in [0,2,1,3,5]], file=infile, sep='\n')
