python编程问题

# coding=utf-8
A = 2
print(A)

word = 'words' * 3
print(word)
word = 'a long word '
mun = 16
string = 'bang!'
total = string * (mun - len(word))
print(total)

a = 'friends'
find_the_evil_in_your_friends = a[0] + a[2:4] + a[-3:-1]
print(find_the_evil_in_your_friends)

b='18811406334'
b1=b.replace(b[:8],'*'*8)
print(b1)

search='16'
a='1386-168-0006'
b='1681-222-0006'
print(search + ' is at '+ str(a.find(search))+ ' to '+ str(a.find(search)+len(search))+' of a ' )
print(search + ' is at '+ str(b.find(search))+ ' to '+ str(b.find(search)+len(search))+' of b ' )

print('{} a is a {}'.format('With','word'))

city = input("yinchuan")
url = "The city is {}".format(city)

city = input("yinchua")
url = "The city is {}".format(city)

def f(c):
f-=c*9/5+32
return str(f)+'f'
c1=f(35)
print (c1)


运行这段Python代码时，只运行到第一个url = "The city is {}".format(city)，之后的无法显示结果，请问是什么原因？请大神指教

这个在哪里输入啊？下面不是直接显示'Yinchuan'了吗？

把f-=那个改成f= 其它的，执行py文件，如下：(你自己对比下，它停住的时候有光标闪动，直接输入就可以)

C:\Users\zzzz>python3 D:/testP/tt.py

bang!bang!bang!bang!

16 is at 5 to 7 of a
16 is at 0 to 2 of b
With a is a word

1，city = input("yinchuan")这2个input是你要输入，才会下一步（这就是它为什么停住的原因） 2，f-=c*9/5+32，这一句有问题，你f没有声明，它没法进行-=操作
