我有一项任务,我必须询问用户是否要将新学生添加到某个程序中。 我设置一个变量来保存用户命令,然后: 如果是(1),程序将要求用户输入名称和ID,否则,程序将退出。
students = []
def get_students_titleCase():
students_titleCase = []
for student in students:
students_titleCase = student["name"].title()
return students_titleCase
def print_students_titlecase():
students_titleCase = get_students_titleCase()
print(students_titleCase)
def add_student(name , student_id = 000):
student = {"name" : name , "student_id": student_id }
students.append(student)
user_command = input("Do You Want to Add a Student Name?\n1- Yes\n2- No\n")
#user_command = 1
if user_command == 1:
student_list = get_students_titleCase()
student_name = input("Enter Student Name: ")
student_id = input("Enter Student ID: ")
add_student(student_name, student_id)
print_students_titlecase()
答案 0 :(得分:1)
如果在python2.7
上执行,则行为将按预期执行,但由于其Python 3
input
返回str
类型raw_input
类似python 2.7
返回raw_input
}。另请注意,python 3
中引入了# Compare against string instead of int
if user_command == '1':
。
因此,考虑到上述观点,您必须稍微更改一下代码才能使其正常工作。
int
但是,如果您仍想与if user_command.isdigit() and int(user_command) == 1:
类型的数量进行比较,那么
cd usr
cd home
FOLDERS=*
L=".bash_login"
P=".bash_profile"
for f in $FOLDERS
do
cd "$f"
if [ -f ".bash_login" ]
then
grep "/etc/runner" $L >/dev/null
if [ $? -eq 0 ]
then
#use swap ex
ex $L <replace.ex
echo "replaced"
else
ex $L <insert.ex
echo "inserted"
#use insert at end ex
fi;
else
grep "/etc/runner" $P >/dev/null
if [ $? -eq 0 ]
then
# use swap ex
ex $P <replace.ex
echo "replaced"
else
ex $P <insert.ex
echo "inserted"
fi;
fi;
cd ..
done
