在字符串的末尾给予一个空格

return "I am super excited for this course! "*5

在这种情况下，您可能需要str.join

def show_excitement():
    return ' '.join(['I am super excited for this course!'] * 5)

示例

>>> show_excitement()
'I am super excited for this course! I am super excited for this course! I am super excited for this course! I am super excited for this course! I am super excited for this course!'

将print(str)移动到行首

for x in range(5):
    str =  str + " "
print(str)

最简单的方法

def show_excitement():
    # Your code goes here!
    string="I am super excited for this course! " *5 
    return string

print show_excitement()

你可以这样做：

def show_excitement():
        s=""
        # Your code goes here!
        for i in range(0,5):
            s+='I am super excited for this course!'+" "
        return s
    
    print show_excitement()

def show_excitement(str,n):
    global result
    if(n==0):
        return result.strip()
    else:
        result=result+" "+str
        return show_excitement(str,n-1)

result = ""
str="I am super excited for this course!"
print show_excitement(str,5)

def show_excitement():
  string = "I am super excited for this course! "
  return "\"{} {} {} {}{}\".".format(string,string,string,string,string)

print（show_excitation（））在此输入代码'
