问题遇到的现象和发生背景
最近在用python编写一个机器人的正解程序，通过读取数据进行正解计算，并将计算出的数据输出到文档
用代码块功能插入代码，请勿粘贴截图
import numpy as np

T23 = np.dot(T12, T4)
T34 = np.dot(T23, T5)
T45 = np.dot(T34, T6)
for i in range(len(T45)):
f1.write(str(T45[i]) + '\n')
运行结果及报错内容
程序能够正常运行，结果可以正常输出，但是运行结果前有空格。
我的解答思路和尝试过的方法
使用 strip 但是未能清楚两端空格
我想要达到的结果
输出的结果没有空格存在
