我想知道爲什麼我的代碼不工作。我想在小數點後用2個數字來舍入兩列數據。我下面就在這時下面的代碼:Python - 格式化ascii表的數字
from __future__ import print_function
with open('input.dat', 'r') as f, open('output.txt', 'w') as outfile:
for line in f:
try:
line = line.strip()
columns = line.split()
vx = float(columns[0])
vy = float(columns[1])
print("{:.2f\t}".format(vx),"{:.2f}".format(vy), file=outfile)
except ValueError:
print(line, file=outfile)
輸入數據就像下面
XY
HH
M&M
TS
1.83746 2.12131
1.12121 1.89942
1.32435 1.99443
1.65392 2.00001
1.48732 2.21773
...
...
輸出應該像下面:
XY
HH
M&M
TS
1.84 2.12
1.12 1.90
1.32 1.99
1.65 2.00
1.49 2.22
