使用spyder编写和保存txt文件

Question

我正在尝试从Python编写一个txt文件：

for i in range(len(X)):
    k+=1
    g.write('CoordinatesX='+str(i)+str(X[i])+'\n')
    g.write('D'+str(k)+'@Sketch'+str(sketch_number)+'=CoordinatesX'+str(k)+'\n')
    k+=1
    g.write('CoordinatesY='+str(i)+str(Y[i])+'\n')
    g.write('D'+str(k)+'@Sketch'+str(sketch_number)+'=CoordinatesY'+str(k)+'\n')
    k+=1
    g.write('CoordinatesZ='+str(i)+str(Z[i])+'\n')
    g.write('D'+str(k)+'@Sketch'+str(sketch_number)+'=CoordinatesZ'+str(k)+'\n')
        
g.close()

我没有发现错误，但是当我去查找下载的文件时，我找不到它，也没有写任何东西。有人知道我做错了什么吗？已经谢谢你了。干杯!

在Python中，您可以这样open一个文件：

file = open('file.txt', 'r+')
file.read() # This will return the content
file.write("This file has just been overwritten")
file.close() # This will close the file

更好的做法是使用with/as语法：

with open('file.txt', 'r+') as file:
    file.read()
    file.write("This file has just been overwritten")
# The file is automatically closed (saved) after the with block has ended
