Python字符串搜索并返回子字符串位置

# multiple searches of a string for a substring

# using s.find(sub[ ,start[, end]])

text = 'MSKSASPKEPEQLRKLFIGGLSFETTDESLRSAHFESSSYGSAGRRF'

search = 'SA'

start = 0

while True:

index = text.find(search, start)

# if search string not found, find() returns -1

# search is complete, break out of the while loop

if index == -1:

break

print( "%s found at index %d" % (search, index) )

# move to next possible start position

start = index + 1

//结果：
SA found at index 3
SA found at index 31
SA found at index 41
