反复编辑python脚本文件[重复]

Hossain • 3 年前 • 1448 次点击

大家好,我想检查氨基酸序列的分值,我为其编写了以下代码,效果非常好。但问题是每次我都要编辑文件。我能从命令界面给出氨基酸序列吗。

AA_seq='AVTLSPQRS' # this is the input variable
sum=0

value={"V": 3.1,"Y":3.5,"W":4.7,"T" :5.3,"S":5.1,"P":3.7,
"F":4.7,"M":1.5,"K":8.9,"L":6,"I":4.3,"H":3.3,"G":7.1,
"E":7,"Q":5.4,"C":0.6,"D":7.6,"N":6,"R":8.7,"A":3.4}

print("Total length of sequence is:", len(AA_seq))
for i in AA_seq:
    
    sum+=value[i]


print("Total Score is :", sum)

您可以从中的命令行轻松访问字符串参数 sys.argv (出于历史原因, sys.argv[0] 包含脚本本身的名称,所以忽略它。

import sys

for AA_seq in sys.argv[1:]:
    value={"V": 3.1,"Y":3.5,"W":4.7,"T" :5.3,"S":5.1,"P":3.7,
"F":4.7,"M":1.5,"K":8.9,"L":6,"I":4.3,"H":3.3,"G":7.1,
"E":7,"Q":5.4,"C":0.6,"D":7.6,"N":6,"R":8.7,"A":3.4}
    print("Total length of sequence", AA_seq, "is:", len(AA_seq))
    for i in AA_seq:
        sum+=value[i]
    print(AA_seq, "Total Score is :", sum)

你会注意到我添加了一个循环,这样你就可以在一次运行中处理多个序列。

接受来自命令行的输入使您能够使用shell的各种功能(制表符完成、历史记录、变量扩展等),以及从其他脚本以编程方式使用此脚本。

如果我能很好地理解你的问题,你可以使用python的“输入”函数来完成。这将使您能够从CLI提供输入。下面是修改代码。

希望这对你有帮助。此外,如果你想避免输入小盘股/股骨头,你可以使用。上()。

虽然这不是这个问题的必要条件。

AA_seq=input("write Amino Acid Sequence:" )
AA_seq=AA_seq.upper()

sum=0

value={"V": 3.1,"Y":3.5,"W":4.7,"T" :5.3,"S":5.1,"P":3.7,
"F":4.7,"M":1.5,"K":8.9,"L":6,"I":4.3,"H":3.3,"G":7.1,
"E":7,"Q":5.4,"C":0.6,"D":7.6,"N":6,"R":8.7,"A":3.4}

print("Total length of sequence is:", len(AA_seq))
for i in AA_seq:
    
    sum+=value[i]


print("Total Score is :", sum)
