Python切片

1. 对list进行切片

L = range(1, 101)

print L[:10]

print L[2::3]

print L[4:50:5]

2. 倒序切片

L = range(1, 101)

print L[-10:]

print L[-46::5]

3. 对字符串切片

def firstCharUpper(s):

    return s[0].upper() + s[1:]

print firstCharUpper('hello')

print firstCharUpper('sunday')

print firstCharUpper('september')
