I am facing an issue while using a global variable x as a counter in my for loops. I have two lists, col_values_X_right and col_values_Y_right, which store coordinates. I intend to create 15 different plots using these coordinates, as the '-' separators within them indicate new chapters of data obtained from another source. However, I am struggling to utilize my global counter variable within the loops. I attempted to use global x, but encountered the error message
SyntaxError: name 'x' is assigned to before global declarationx = 0
for j in range(number_of_separatores//2):
image_plot1 = plt.imshow(image1)
global x
for i in range(len(col_values_X_right)-x):
if stimulus_name[x+1] == '5_01.jpg' and col_values_X_right[x+1] != '-':
plt.scatter([col_values_X_right[x+1]], [col_values_Y_right[x+1]])
x += 1
else:
break
plt.show()
Additional details:
x = 0 # initializing the counter variable for cycles
a = 15
image = mpl.image.imread('file_name.png')
X = list() # specify float numbers here
Y = list() # include coordinate values here
for j in range(a): # loop for creating multiple plots
image_plot = plt.imshow(image) # display image for plotting
for i in range(len(X)): # iterating through coordinate columns separated by '-'
if X[x+1] != '-':
plt.scatter([X[x+1], Y[x+1]) # plot a point based on coordinates
x+=1 # move to the next column cell for the next iteration
else:
break # stop plotting current plot and move to the next one upon encountering '-'
plt.show()
