알고리즘 sequential search(순차검색) - Python3 파이썬

발견하면 location 출력

발견못하면 -1 출력

def seqsearch(s,x):
    location = 1
    while (location <=len(s) and s[location-1] != x):
        location +=1
    if location > len(s):
        location = -1
    return location

s = [3,5,2,1,7,9]
loc = seqsearch(s,4)
print(loc)
