Question

我想运行一个python文件file.py 20次，1000次迭代，单次运行点击，这样我就不需要手动点击运行20次。

Init()
globalBest=pop[0].chromosome

# Saving Result

fp=open(resultFileName,"w");
fp.write("Iteration,Fitness,Chromosomes\n")

for i in range(0,iterations):
    Crossover()
    Mutation()
    MemoriseGlobalBest()

    if funEval >=maxFunEval:
        break

  if i%20==0:
     print "I:",i,"\t Fitness:", bestFitness
     fp.write(str(i) + "," + str(bestFitness) + "," + str(bestChromosome) + "\n")

print "I:",i+1,"\t Fitness:", bestFitness
fp.write(str(i+1) + "," + str(bestFitness) + "," + str(bestChromosome))    
fp.close()

Answer 1

您可以编写另一个脚本，将脚本调用20次。制作一个循环并在其中调用file.py 20次。

Answer 2

尝试：

for iteration in range(20):
    Init()
    globalBest = pop[0].chromosome

    # Saving Result

    fp = open(resultFileName, "a")
    fp.write("Iteration,Fitness,Chromosomes\n")

    for i in range(0, iterations):
        Crossover()
        Mutation()
        MemoriseGlobalBest()

        if funEval >= maxFunEval:
            break

    if i % 20 == 0:
        print
        "I:", i, "\t Fitness:", bestFitness
        fp.write(str(i) + "," + str(bestFitness) + "," + str(bestChromosome) + "\n")

    print
    "I:", i + 1, "\t Fitness:", bestFitness
    fp.write(str(i + 1) + "," + str(bestFitness) + "," + str(bestChromosome))
    fp.close()

如何以1000次迭代运行python文件20次
