我想在文本文件中打印一个巨大的数字列表，每行应该有5个数字。每个数字都是20位数。
下面是数字列表（这个巨大的数字列表叫做a1）

假设a1是列表然后尝试： -
fl = open('testfile5.txt',"w")
count = 0
with open('ddd.txt','r') as f:
line = f.read()
line = line.strip().split()
for i in range(5,len(line)+1,5):
result = ''.join(str(line[count:i]))
fl.write(result+'\n')
count = i
fl.close()
