英文:
I am generating numbers in a specific range with a specific stepsize and saving to a .txt file. But I want to save the filename in a specific format. I present the current and expected output.
Start=0
End=500001
Stepsize=1000
for i in range(Start,End,Stepsize):
#print(i)
with open('All_values_{Start}_{End}_{Stepsize}.txt', 'a') as f:
#writer = csv.writer(f)
#print(" =",i)
f.writelines('\n')
f.write(str(i))
The current output in terms of file naming is
All_values_{Start}_{End}_{Stepsize}
The expected output is
All_values_0_500001_1000
