Python代码缩进问题求助：添加141-142行后触发IndentationError

在完成编程作业时，给main()函数添加以with开头的两行代码后，出现了IndentationError（缩进错误）。我已花费大量时间排查却找不到问题，朋友的相似代码却能正常运行。

我尝试把with相关的文件读取功能移到独立函数中，在main()里调用后还是出现同样的缩进错误。我的需求是通过with语句将指定文件的所有内容存入数组。

已尝试的解决步骤 #

• 对比朋友的相似代码，对方代码可正常运行
• 将with相关功能移至独立函数，main调用后仍报相同缩进错误

# Use open file to store the lines with their indicies
# When beq or bne compare and if it's true -> grab the label imm -> convert to decimal
# -> divide by 4 to get actual line

# Ad

# While i less than size of array of lines go one by one and do logic
#   storedLines[i] - line of a code in a file. Do logic to each [i]
# Add internal pc counter (intpc=0). By each iteration of i intpc goes +4
# at the end  of while loop internalPC = 4
# i == internalPC // 4
