Python while循环在10个循环后停止

Question

我有 python lcg 生成器（随机）并运行测试功能，但我的 while 循环在第 10 个循环后停止，即使我有条件 True 永远不会停止帮助 guyzzz

import math
def rng(m=2**32, a=1664525, c=1013904223):
    rng.current = (a*rng.current + c) % m
    return rng.current/m

def runs(fragma):
    run=0
    
    while True:
        x=rng()
        if x<=fragma:
            run+=1            
        else:
            return run
    return run    

# setting the seed
rng.current = 0
u=[]
for i in range(0,100,1):
    u.append(rng())
mean=sum(u)/len(u)
variance=sum(pow(x-mean,2) for x in u) / len(u)
standartdeviation=math.sqrt(variance)

print("meso oro:",mean)
print("tipiki apoklisi : ",standartdeviation)

rng.current = 0
i=0.0
y=0
while True: -----------------------------this loop
    #rng.current = rng()
    i+=0.1
    y+=1
    print(y)
    x=runs(i)
    print("for fragma=",i,"--runs==",x)

当x<=fragma 时，您不会在runs(fragma) 函数中返回任何内容：

while True:
    x=rng()
    if x<=fragma:
        run+=1
        return run  # <---
    else:
        return run
