python break和continue

# break，代表终止，如果循环遇到break则终止，必须放在循环内部


a = 0
while a<100000:
    str1 = input("请输入一个字符串")
    if str1 == "exit":
        break
    print(str1)
    a +=1

# 指定超过5暂停
a = 0
b = int(input("请输入一个值"))
while a < b:
    print("*")
    a += 1
    if a >= 5:
        break

# continue

a = 0
while a < 5:
    a += 1
    if a ==3:
        continue
    print(a)
