Python开发笔记：深入探讨字符串及其常用方法与技巧

# 将字符串中的每个元素，按照指定分隔符进行拼接
# 空格 、# 、_ 等等 不能是反斜杠
test = ‘你是风儿我是沙‘
ret = ‘#‘.join(test)
print(ret)

# 去除字符串左右两边的空格
test = ‘ alex ‘
ret = test.strip()
print(ret)

test = ‘alex‘
ret = test.strip(‘ax‘)
print(ret)

# 字符串分割，包含判断的字符，并且是3部分
test = ‘xalelx‘
ret = test.partition(‘l‘)
print(ret)

# rpartition 是从最后一位开始查找，找到并分为3部分
test = ‘xalelx‘
ret = test.rpartition(‘l‘)
print(ret)

test = ‘xalelxlelelelele‘
ret = test.split(‘l‘)
print(ret)

test = ‘xalelxlelelelele‘
ret = test.split(‘l‘,2)
print(ret)

test = ‘alex‘
ret = test.replace(‘ex‘,‘abc‘)
print(ret)

test = range(0,100,5)
for i in test:
print(i)
