'数字.int64'对象不是callab'

Question

我只是在工作中写了一个代码，突然我有了这个我无法解决的错误。这个程序由不同的Python模块和文件组成，但是即使我注释掉import语句，让我用print()运行这个程序，我也会得到这个错误。即使我打开一个新文件，只写print("Hello World")什么都不写，我也会收到这个错误。你知道吗

#from analyzeData.analyzeData import AnalyzeData
#from clustering.fancyPrcnt import fancyPrcnt
#from clustering.sampleData import SampleData

x = 10000
y = True  
z = "variable_x"
a = "variable_a"
b= "variable_b"

print('Print')

错误是：

runfile('C:/Users/yc06664/Desktop/untitled4.py', wdir='C:/Users/yc06664/Desktop')
Traceback (most recent call last):
