python作业（三）

# 有变量name = "aleX|eNb"完成如下操作：
# 移除name变量对应的值两边的空格，并输出结果
name = "               aleX|eNb "
print(name.strip(" "))
print(name)

# 移除name变量左边的al并输出处理结果
name = "aleX|eNb "
print(name.lstrip("al"))
print(name)

# 移除name变量右边的Nb,并输出处理结果.
name = "aleX|eNb"
print(name.rstrip("Nb"))

# 移除name变量幵头的a与最后的b并输出处理结果
name = "aleX|eNb"
print(name[1:-1])

# 判断name变量是否以"al"开头，并输出结果
name = "aleX|eNb"
print(name.startswith("al"))

# 判断name变量足否以Nb结尾.并输出结果
name = "aleX|eNb"
print(name.endswith("Nb"))

# 将name变逭对应的值中的所有的|替换为“p”,并输山结果
name = "aleX|eNb"
print(name.replace("|", "p"))
# 将name变谊对应的值中的第一个|替換成p并输出结果
name = "a|eX|eNb"
print(name.replace("|", "p", 1))

# 将name变虽对应的值根据所有的|分割,并输出结果。
name = "a|eX|eNb"
print(name.split("|"))

# 将name变蜇对应的也SE第一个I分割，并输出结果<•.

# 将name变量对应的值变大写，并输山结果__
name = "aleX|eNb"

# 将name变盘对应的值变小写，并输出结果13>

#  将name变量对应的首个字母^大写 输出结队

# 判断name变最对应的值字母l出现几次，并输出结果-
name = "aleXleNb"
print(name.count("l"))
# 判断name变量对应的值前四位l出现了几次 并输出结果
name = "aleXleNb"
print(name.count("l", 0, 3))

# 从name变量对应的值中找到N对应的索引 如果找不到 报错

# 输出name的第二个字符

# 输出name的前三个字符
print(name[0:3])

# 输出name的后两个字符
