[英]How to get multiple lines from a .txt file that have been split and to save them into different variables
[英]How can I read values from a .txt-file and save them into different variables in python and get access to them?
我是新的學習編碼。 我正在嘗試讀取包含多行的文件。 線條具有 x,y 坐標值。 最后一個數字 z 是一些隨機數額的錢。 我想將它們保存在列表中的不同變量中。 例如,我的.txt-file
是這樣的,只是多了幾百行:
0,3,97.72
0,4,97.69
0,5,97.66
我希望它逐行保存,如下所示: x = 0 y = 3 z = 97.72
當我然后 select 兩個隨機坐標時,我想得到它們之間的所有坐標和 plot 所有 z 值與matplotlib
。 我怎樣才能做到這一點?
我試圖用 for 循環保存值,但失敗了。 編輯:這是我的嘗試:
with open(f"example.txt", "r", encoding=ascii) as lines:
coordinates=[]
for line in lines:
x_text,y_text, z_text = line.split(",")
coordinates.append((int(x_text), int(y_text), float(z_text)))
for x, y in coordinates:
if x_text ==x and y_text <= y <=y_text:
print()
elif x_text <= x <=x_text and y_text == y:
print()
您似乎能夠將文件數據讀入坐標列表,因此我假設您的問題在於確定給定坐標是否在某種邊界框內。
嘗試:
def falls_between(coord, top_left, bottom_right):
return top_left[0] <= coord[0] <= bottom_right[0] and top_left[1] <= coord[1] <= bottom_right[1]
test_top_left = (0, 0)
test_bottom_right = (4, 4)
coordinates=[]
with open("in.csv", "r") as file_in:
for row in file_in:
x, y, z = row.strip("\n").split(",")
coordinates.append([int(x), int(y), float(z)])
for coord in coordinates:
if falls_between(coord, test_top_left, test_bottom_right):
print(f"{coord} is inside {test_top_left} and {test_bottom_right}")
else:
print(f"{coord} is not inside {test_top_left} and {test_bottom_right}")
